Erectile Dysfunction Treatment in NZ (2026): Every Option Compared, With Costs
Based on the clinical experience of Dr Mark Morunga, NZ-registered doctor, Magna Clinical Lead. Last updated October 2026.
If you want the short version: erectile dysfunction (ED) is treatable for most men. The first-line treatment in New Zealand is a prescription tablet, it works for roughly three in four men who try it, and you can get it through your GP, a pharmacist (with age limits) or an online doctor service, from about $39 a month with the consult and delivery included. Everything else, from lifestyle changes to injections to implants, has its place, and this guide covers all of it so you can see where you fit.
Erectile dysfunction treatment: the short answer
| If this is you | Start here |
|---|---|
| Erections are unreliable but not gone, and you're otherwise healthy | A PDE5-inhibitor tablet (sildenafil or tadalafil), prescribed after a doctor has checked your heart health and medications |
| You want sex to be spontaneous, not scheduled | Daily low-dose tadalafil, or on-demand tadalafil, which lasts up to 36 hours |
| It started suddenly, you still wake with erections, and it's worse with a new partner or under stress | Likely a psychological component. Tablets still help, and a few sessions with a sex therapist often fix the pattern |
| You're under 40 and it's gradual | See a doctor. It can be an early sign of cardiovascular or metabolic problems, and it's very treatable |
| Tablets haven't worked after 6–8 properly timed attempts at the right dose | Second-line options: a different tablet, penile injections, a vacuum device, or a urology referral |
| You take nitrate medication for angina or chest pain | Tablets are off the table. Talk to your GP or a urologist about alternatives |
What this guide covers: every erectile dysfunction treatment available in New Zealand, how well each one works according to the evidence, what each one costs here, how to actually get it (GP, pharmacist or online doctor), and the safety rules that matter.
What erectile dysfunction is, and why it happens
Erectile dysfunction is the persistent inability to get or keep an erection firm enough for sex. The word that matters is persistent. Every man has an off night. It’s erectile dysfunction when it happens regularly over weeks or months, or when it has started to change how you approach sex.
How common is ED in New Zealand?
Common enough that it shouldn’t be embarrassing. A large share of Kiwi men will deal with it at some point, and the odds rise with age: in the large Massachusetts Male Aging Study, about 40% of men had some degree of erectile dysfunction at 40 and nearly 70% by 70. It’s also increasingly seen in men in their 20s and 30s, where the cause is more often stress, anxiety, alcohol or sleep than blood vessels.
An erection is a plumbing event. Arousal signals the arteries in the penis to relax and fill with blood, and the veins to clamp shut to hold it there. Anything that interferes with the nerves, the blood vessels, the hormones or the brain’s signal can cause erectile dysfunction:
- Blood vessels (the most common cause over 40). High blood pressure, high cholesterol, diabetes, smoking and being overweight all narrow or stiffen the small arteries in the penis. These are the same arteries that feed the heart, just smaller, which is why they fail first.
- Medications. Some blood pressure tablets, many antidepressants (SSRIs especially), finasteride in a small minority of men, and some prostate medicines. If the problem started when a prescription did, raise it with whoever prescribed it.
- Hormones. Low testosterone is a less common cause than people assume, but it matters when it’s present, and it usually comes with low libido and low energy, not just erection problems.
- Nerves. Diabetes, prostate surgery, spinal injury, multiple sclerosis.
- The head. Performance anxiety, stress, depression, relationship strain, and a feedback loop where one bad night makes the next one more likely. The tell: if you still wake with erections or have no trouble alone, the hardware works and the cause is at least partly psychological. That’s good news, because it responds well to treatment.
- Lifestyle. Alcohol (reliably, and in the moment), smoking, inactivity, poor sleep, and recreational drugs.
The one thing every man with ED should know. Erectile dysfunction is often the first symptom of cardiovascular disease, showing up two to five years before chest pain or a heart attack, because the penile arteries are narrower than the coronary ones and block first. If you’re over 40 and it has crept in gradually, the right response isn’t just a tablet. It’s a blood pressure check, a cholesterol test and a blood sugar test. Any doctor treating your erectile dysfunction properly, Magna’s included, will ask about these.

Costs are New Zealand dollars, approximate, October 2026. No erectile dysfunction tablet is Pharmac-funded, so the medicine costs money whichever route you use. Third-party prices vary by pharmacy, clinic and dose. Magna’s are its current plan prices with the doctor consult and delivery included. See pricing.
ED tablets: sildenafil and tadalafil
These medicines are the first-line erectile dysfunction treatment in every major guideline, and they’re what most New Zealand men end up on. They’re PDE5 inhibitors: they relax the blood vessels in the penis so that when you’re aroused, more blood flows in and stays there. They don’t create an erection on their own, they don’t raise libido, and they only do anything when you’re turned on. That’s why they feel natural when they work.
Sildenafil
Is the original (Viagra) and the one most men start on. Take it 30 to 60 minutes before sex and it stays active for four to six hours. A heavy or fatty meal slows it down, and alcohol works against it regardless. Your doctor sets the dose and adjusts it if the first one isn’t quite right. In New Zealand it’s also the only ED tablet a pharmacist can supply without a prescription, to men aged 35 to 70 after a screening consultation.
Tadalafil (Cialis)
Is the long one. Taken on demand it lasts up to 36 hours, which is why couples like it: you take it on Friday and the weekend is covered. Food doesn’t affect it. The other way to use it is a low daily dose, which keeps a steady level in your blood so there’s nothing to time and nothing to plan. After three to five days you’re simply ready whenever. Daily tadalafil also eases the urinary symptoms of an enlarged prostate, which makes it a sensible choice for men over 50 who have both. Like sildenafil, it isn’t funded in New Zealand, so you pay for it whichever route you take; the online plans bundle it with the consult and delivery.
Avanafil (Spedra)
Is the newest and fastest of the three, working in about 15 to 30 minutes, and some men who get headaches on the others tolerate it better.
Daily or on demand?
On demand suits men who have sex a couple of times a week or less and don’t mind a little planning. Daily suits men who want spontaneity, have sex more often, have prostate symptoms too, or find that the act of taking a tablet “before” feeds their anxiety. Plenty of men try both over a year. A doctor who treats erectile dysfunction regularly will match the tablet to how you have sex: on demand when it’s occasional and predictable, daily or long-acting when you want spontaneity, and a switch to the other tablet if timing, duration or side effects are the problem.
What to expect
Most men get a result in the first few doses, but not everyone does, and the single biggest reason tablets “don’t work” is giving up after one or two attempts at a dose that was too low or taken too late. Give it six to eight properly timed tries before deciding; the dose can be adjusted. The common side effects are a headache, facial flushing, a blocked nose, indigestion, and with sildenafil a temporary blue tinge to vision; with tadalafil, back or muscle aches. They’re usually mild and pass as the drug clears. Stop and get urgent help for an erection that lasts more than four hours, sudden loss of vision or hearing, or chest pain.
When tablets aren’t enough: other ED treatments
About one man in four doesn’t get a good enough result from tablets, usually because the blood vessels or nerves are more damaged (long-standing diabetes, prostate surgery, heavy smoking history) or because tablets aren’t safe for him. These are the next steps, in the order a urologist would usually suggest them.
Penile injections (alprostadil). A tiny injection into the side of the penis a few minutes before sex produces an erection in most men, including many for whom tablets failed, and it works without arousal. It sounds worse than it is: the needle is very fine and most men say it’s less uncomfortable than they feared. It needs a specialist to teach the technique and set the dose, and it’s available in New Zealand on prescription. The risks are bruising, a prolonged erection if the dose is too high, and over years, scarring at the injection site.
Vacuum erection devices. A cylinder over the penis, a pump to draw blood in, and a constriction ring at the base to keep it there. Mechanically it works for most men and it’s drug-free, which matters if you’re on nitrates. The trade-offs are a cold, slightly numb erection, a ring that can only stay on for 30 minutes, and a lack of spontaneity. Useful as a backup and for men who can’t take anything.
Low-intensity shockwave therapy. Sound-wave pulses applied to the penis, with the theory that they stimulate new blood vessel growth. Private clinics in Auckland, Wellington and Christchurch offer it at several hundred dollars a session. The honest state of the evidence: some small trials show modest improvement in mild vascular erectile dysfunction, others show nothing. The American Urological Association still classes it as investigational, and the European guideline gives it only a weak recommendation for mild cases. If you try it, go in knowing you’re paying for an experiment.
Testosterone. Replacement only helps when testosterone is genuinely low on a morning blood test and you have the other symptoms, such as low libido, low energy and loss of muscle. On its own it rarely fixes erections; it’s more often used alongside a tablet. Men with normal testosterone get nothing from it but the risks.
Penile implants. Surgery to place an inflatable device inside the penis. It’s the last resort, it’s irreversible, and it has the highest satisfaction rate of any erectile dysfunction treatment, around 90%, because it simply works every time. Privately in New Zealand it costs in the region of $20,000 to $30,000; public funding exists but is limited.
Treating erectile dysfunction without medication
For mild cases, and alongside tablets for everyone else, three things have real evidence behind them. None of them is a substitute for a doctor’s check of your heart health, but all of them make every other treatment work better.
Exercise, weight and the things you already know. This isn’t a platitude; it’s the most studied non-drug ED treatment there is. A 2018 review of the trials found that 40 minutes of moderate aerobic exercise four times a week for six months improved erectile function in men whose cause was vascular, obesity, inactivity or metabolic. In a well-known Italian trial, a third of obese men regained normal erectile function in two years through diet and exercise alone. Stopping smoking improves it within months. Cutting alcohol helps on the night and over time. Sleep apnoea, common in men who snore and wake unrefreshed, is a frequently missed cause, and treating it often fixes the erections too.
Pelvic floor exercises. The same muscles women are told to train after childbirth sit at the base of the penis and help trap blood in an erection. In a British randomised trial, three months of daily pelvic floor training plus lifestyle advice restored normal erections in about 40% of men with erectile dysfunction and improved another 35%. A men’s health physiotherapist can teach the technique in one session, or you can learn it from a reputable guide: find the muscle that stops urine mid-stream, contract it for a few seconds, release, repeat in sets, daily.
Talking treatment. If erectile dysfunction started suddenly, happens with a partner but not alone, is worse with a new partner or under stress, or you still wake with erections, anxiety is driving at least part of it. Performance anxiety is self-reinforcing: one failure makes you watch yourself the next time, and watching yourself is the opposite of arousal. A psychosexual therapist or a psychologist experienced in sexual health breaks that loop, often in a handful of sessions. The trials consistently show that therapy plus a tablet beats either alone, because the tablet gives you a few guaranteed successes while the therapy stops you needing it.
What doesn’t work. Herbal and “natural” erection supplements have no good evidence, and Medsafe regularly issues alerts about products sold online as natural that turn out to contain undeclared sildenafil or tadalafil at unknown doses. If a supplement works like a prescription drug, it probably is one. Testosterone boosters, horny goat weed, L-arginine and ginseng have small or inconsistent trials behind them at best.
Dealing with premature ejaculation as well? Many men have both, and the two are often treated together. See premature ejaculation treatment.
What erectile dysfunction treatment costs in New Zealand
No erectile dysfunction tablet is funded by Pharmac, so the medicine costs money whichever door you use, and the tablets are the affordable end of the range either way. What changes between routes is how the cost is split: an online doctor bundles the consult, the prescription and delivery into one monthly price, while the GP route splits it into an appointment fee, the pharmacy counter every three months, and another appointment when the script runs out. Everything else sits well above.
| Route | What you pay | Notes |
|---|---|---|
| GP visit + sildenafil | $45–80 per appointment, then the pharmacy price every three months | Requires the appointment, the conversation and time off work, then a pharmacy trip every three months and a new appointment when the script runs out. The right route if you also need a physical examination |
| GP visit + tadalafil | Appointment as above, then the pharmacy price, typically $40–90 a month depending on dose and how often you use it | Prices vary noticeably between pharmacies; ask |
| Pharmacist-only sildenafil | Roughly $40–60 for a pack of four | Men 35–70 only, after a screening consultation; no prescription needed; the pharmacist may refer you to a doctor |
| Online doctor (Magna) | From $39 a month for the on-demand option and from $65 a month for the daily option, on a 3-month plan; consult, prescription, repeats and delivery all included, no appointment fee | NZ-registered doctor, free discreet delivery, dose changes at no cost; pause or cancel any time |
| Sex therapist / psychologist | $150–250 a session, typically 4–8 sessions | Some employers' EAP schemes cover it |
| Men's health physio (pelvic floor) | $90–130 for an assessment | One or two sessions is usually enough |
| Urologist (private) | $250–400 initial consult | For injections, devices, implants, or when tablets have failed |
| Penile injections | $15–25 per injection plus the specialist's fees | |
| Vacuum device | $150–400 one-off | |
| Shockwave therapy | $250–500 a session, 6–12 sessions | Investigational; see above |
| Penile implant | $20,000–30,000 private | Limited public funding |
Two honest notes on price. First, compare the whole cost, not the tablet: the appointment fee, the pharmacy trip every three months, the new appointment when the script runs out, and the conversation many men keep putting off are all part of the GP price. An online consult at $39 a month includes all of that, and the man who actually starts treatment this month is better off than the one with a good intention he never acts on. Second, whichever route you take, the medicine is the smaller part of the cost. The consult is what makes it safe, and the follow-up is what makes it work.
How to get erectile dysfunction treatment in NZ
There are three doors, and the right one depends on how you feel about the conversation.
1. Your GP
The traditional route, and the right one if you have other health problems that need a hands-on examination. A good GP will take your blood pressure, go through your medications, ask about chest pain and exercise tolerance, and often order cholesterol and blood sugar tests, because erectile dysfunction is a reason to look at the heart. Then a prescription for up to 12 months, a trip to the pharmacy counter every three months, and another appointment when it runs out. The drawback is the one everyone knows: you have to book, sit in the waiting room, and say it out loud to someone who may have known you since you were twelve. Many men put that off for years.
2. A pharmacist
Since 2014, trained pharmacists in New Zealand can supply sildenafil without a prescription to men aged 35 to 70 after a private screening consultation. It’s quick and anonymous, but it’s sildenafil only, it’s limited to small packs, there’s no doctor review of your overall health, and if you’re under 35, over 70, or have any cardiovascular flags, the pharmacist has to send you to a doctor anyway.
3. An online doctor
This is what Magna does. You answer a short medical questionnaire, a New Zealand-registered doctor reviews your assessment and you have a short consult with the Magna team (the questions are the same ones a GP would ask, just without the waiting room), and if treatment is appropriate the medicine arrives at your door in plain packaging. Magna’s clinical lead is Dr Mark Morunga of Essential Men’s Clinic in Auckland, and there are three plans:
- Main Event: taken when you need it, the well-established choice when you know sex is likely. From $39 a month.
- Ever Ready: the daily, longer-lasting option that keeps you ready without planning. From $65 a month.
- Turbo: a convenient option for men who want treatment closer to the moment, with less planning.
Dose changes are free, you can switch between options, and you can pause or cancel whenever you like. The doctor decides what’s prescribed; the questionnaire doesn’t. If the consult turns up something that needs a GP or a specialist, you’ll be told, not sold to.
Whichever door you choose, don’t skip the medical conversation. The tablets are safe for most men precisely because someone checked that they’re safe for you.
Safety: who shouldn’t take ED tablets
Sildenafil and tadalafil are well tolerated by most healthy men, and the serious risks are specific and avoidable.
- Never with nitrates. GTN spray or tablets, nitrate patches, isosorbide mononitrate or dinitrate, nicorandil: all used for angina and some heart conditions. Combined with a PDE5 inhibitor they can drop your blood pressure dangerously. This is the one absolute rule.
- Never with poppers. Amyl nitrite and similar recreational inhalants are nitrates too, and the combination has caused deaths.
- Recent heart attack or stroke, unstable angina, or heart failure where sex itself is unsafe: a doctor needs to assess you before any treatment, including the tablets.
- Alpha blockers for prostate or blood pressure (tamsulosin, doxazosin and similar) can be combined, but the doses need spacing and a doctor’s oversight.
- Some antifungals and HIV medicines (ketoconazole, itraconazole, ritonavir) raise the tablet’s level in your blood; the dose has to be lowered.
- Severe liver or kidney disease, very low blood pressure, and the eye condition retinitis pigmentosa need a doctor’s judgement.
- One tablet, one type, one dose in 24 hours. Never combine two erectile dysfunction medicines, and never take a second dose because the first didn’t work.
- Stop and seek urgent care for an erection lasting more than four hours, a sudden drop in vision or hearing, or chest pain during sex.
On buying tablets online from overseas. Importing prescription medicines into New Zealand without an NZ prescription isn’t permitted, and the parcels are regularly seized. More to the point, the tablets sold by unregulated websites are frequently counterfeit: wrong dose, wrong drug, or no drug at all, and sometimes contaminated. Medsafe publishes alerts on these products every year. An NZ-registered doctor and an NZ pharmacy are the entire difference between a medicine and a gamble.
Erectile dysfunction FAQs
Can erectile dysfunction be cured?
Sometimes. When the cause is reversible, such as a medication, alcohol, weight, sleep apnoea or anxiety, fixing the cause can resolve it completely. When the cause is vascular or nerve damage, it’s managed rather than cured, and the tablets manage it well for most men. Either way, treating it early improves the odds.
What is the best erectile dysfunction treatment in New Zealand?
For most men, a PDE5-inhibitor tablet prescribed after a proper medical check. Which one depends on how you have sex: sildenafil for the planned night, daily or on-demand tadalafil for spontaneity. Lifestyle change and, where anxiety is involved, counselling make the tablets work better and sometimes replace them.
Can you buy Viagra over the counter in New Zealand?
Not exactly. Sildenafil (the medicine in Viagra) can be supplied by a trained pharmacist without a prescription to men aged 35 to 70 after a screening consultation. Men outside that age range, and anyone who wants tadalafil, needs a prescription from a doctor, which can be done online.
Is erectile dysfunction treatment funded in New Zealand?
No. Pharmac doesn’t fund any erectile dysfunction tablet. Sildenafil is on the funded list only for pulmonary hypertension under Special Authority, which doesn’t apply here. Whichever route you take, you pay for the medicine. Specialist treatments such as injections and implants may be publicly funded in some circumstances through a urology referral.
How much does erectile dysfunction treatment cost in New Zealand?
From $39 a month through an online doctor with the consult and delivery included, $40 to $60 for a pharmacist-only pack of four sildenafil tablets, or a GP appointment at $45 to $80 plus the pharmacy price every three months. Injections, shockwave therapy and implants run from hundreds to tens of thousands of dollars.
Can I get erectile dysfunction treatment online in New Zealand?
Yes. Online services with New Zealand-registered doctors can assess you by questionnaire and consult, prescribe sildenafil or tadalafil, and have an NZ pharmacy deliver it. The medical checks are the same as a GP’s; what you skip is the waiting room. If you’re comparing services, see our guide to Hims alternatives in NZ.
Does erectile dysfunction mean I have heart disease?
Not necessarily, but it’s a recognised early warning sign, often appearing two to five years before heart symptoms. If you’re over 40 and it has come on gradually, get your blood pressure, cholesterol and blood sugar checked alongside treating the erectile dysfunction.
I’m in my 20s. Can I take these tablets?
Yes, if a doctor has assessed you and found no reason not to. Erectile dysfunction in younger men is more often driven by anxiety, alcohol or sleep than by blood vessels, so the tablets usually work well and are often a bridge while the underlying cause is sorted out.
What if the tablets don’t work?
First, make sure they had a fair trial: the right dose, taken at the right time, on six to eight occasions, without a heavy meal or much alcohol. Then try the other tablet. If neither works, the next steps are penile injections, a vacuum device, or a urology referral, all of which succeed for most men for whom tablets didn’t.
This article is general information, not medical advice. Erectile dysfunction treatment requires a prescription from a registered doctor who has assessed your individual circumstances.
