Finasteride in NZ: How to Get It, What It Costs, and Propecia vs Generic (2026)
Based on the clinical experience of Dr Mark Morunga, NZ-registered doctor · Updated November 2026
Finasteride is one of the most prescribed hair loss medicine in New Zealand, and the one most Kiwi men search for first. The short version: it's prescription-only here, Pharmac doesn't fund it for hair loss, Propecia and generic finasteride are the same medicine at different prices, and the cheapest way to get it is usually through an online doctor service like Magna, from $49 a month with the prescription and delivery included. Here's everything else you'd want to know before you start.
What finasteride does
Male pattern hair loss is driven by DHT, a hormone your body makes from testosterone. In men who carry the gene for it, DHT slowly shrinks the follicles on the top of the scalp until the hairs they grow are too fine to see. Finasteride blocks the enzyme that makes DHT, cutting scalp DHT by well over half. The follicles stop shrinking, the shedding slows, and in most men the hair thickens back up over the following year.
It's the best-evidenced hair loss treatment there is. Two decades of trials and long-term follow-up show roughly nine in ten men keep the hair they have on finasteride, and around two in three regrow some. For the mechanism in more detail, see what causes hair loss and our guide to how finasteride works and what to expect.
Is finasteride available in New Zealand?
Yes, with a prescription. Finasteride is a prescription medicine under NZ law in every form, so a pharmacist can't sell it to you over the counter and no legitimate website can ship it to you without a New Zealand-registered doctor reviewing you first.Two forms exist here:
- Tablets. Medsafe has approved finasteride tablets at the hair-loss strength since 1997. The original brand is Propecia, made by Organon, and generic versions such as Profal (Teva) are registered as well. A higher-strength finasteride tablet also exists for enlarged prostate; it's a different product for a different job.
- Topical finasteride. There's no Medsafe-registered topical product on the shelf. It's made to order by a New Zealand compounding pharmacy against a doctor's script, usually combined with minoxidil in one solution. We've covered where to get topical finasteride in NZ separately.
Propecia vs generic finasteride
This is the question we get asked most, so here's the plain answer: Propecia is a brand name. The tablet inside is finasteride at the same strength, taken the same way, with the same evidence behind it as a generic finasteride tablet. Medsafe requires generics to be shown bioequivalent to the original, which is why a doctor will happily prescribe either.
What differs is the price. Branded Propecia costs around $45 to $55 a month at NZ pharmacies; generic finasteride at the hair-loss strength is a little less, and prices move around between pharmacies. If you were searching for "buy Propecia NZ", the thing to know is that you can't buy it without a script, and the brand name is not buying you a better result.
One trap to avoid: some men are prescribed the higher-strength prostate tablet and told to cut it into pieces to save money. Dosing by guesswork is a poor idea with any medicine, the pieces are rarely even, and the dust is a real hazard if there's a pregnant woman in the house. A doctor who treats hair loss regularly won't suggest it.
Is finasteride funded in NZ?
Not for hair loss. Pharmac treats male pattern hair loss as cosmetic, so finasteride at the hair-loss strength is unfunded whichever way you get it. The only subsidised finasteride in New Zealand is the prostate tablet, and even that needs Special Authority approval for an enlarged prostate. Healthify summarises the funding position if you want the official wording.
In practice that means the cost comparison is purely between routes, and the route matters more than most men expect.
The three ways to get finasteride in NZ
1. Through your GP. Book an appointment, ask about finasteride for hair loss, and if your GP is comfortable prescribing it you take the script to a pharmacy. It works, but you pay the appointment fee each time the script runs out, you're on your own for follow-up, and many GPs see hair loss rarely enough that topical options and combinations aren't on their radar.
2. Through a dermatologist or hair loss clinic. The most thorough option, and the most expensive. A first private appointment in NZ usually runs $250 to $400, waitlists outside Auckland can be months, and you still collect the medicine yourself.
3. Through an online doctor-led service. With Magna you complete a short online assessment, a New Zealand-registered doctor reviews it and your scalp photos, you have a short call with a Magna team member, and if finasteride is right for you it's prescribed and delivered to your door in plain packaging. Follow-ups, dose adjustments and switching between tablet and topical are included. The doctors reviewing assessments work with hair loss every day under clinical lead Dr Mark Morunga, who has run a hair restoration clinic in Auckland for over a decade.

What to expect once you start
Finasteride is slow and then it's obvious. Shedding usually slows within three to six months. Visible thickening takes six to twelve months, and the best results in the trials were at the two-year mark. Some men notice a short burst of extra shedding in the first couple of months as weak hairs make way for stronger ones. It settles.
It only works while you take it. Stop, and DHT goes back to work; most men are back where they started within a year. That's why the earlier you begin, the more you keep, and why a plan you can actually stick to beats the cheapest script you'll forget to renew.
Side effects, honestly
Most men take finasteride without noticing anything. A small percentage, in the trials around one or two men in every hundred more than on placebo, report lower libido, erection changes or less semen. For most of them it fades with time or stops when the medicine stops. Rarely, men report low mood; if that happens, stop and talk to your doctor.
If side effects are the thing holding you back, you have options rather than a yes-or-no choice. Topical finasteride delivers the DHT block at the scalp with far less reaching the bloodstream, and a doctor can start you on a lower frequency and build up. Finasteride isn't prescribed to women who are or could become pregnant, because it can affect a male baby's development.
Finasteride on its own, or with minoxidil?
Finasteride stops the loss. Minoxidil drives regrowth. For men with early thinning, finasteride alone is often enough. For a receding hairline or thinning crown that's already noticeable, the combination is what hair loss doctors reach for, either as a tablet plus oral minoxidil or as a single compounded topical. Our hair loss treatment guide walks through when each makes sense, and if you're weighing finasteride against its stronger cousin, read finasteride vs dutasteride.
What the trials show
Finasteride is one of only two medicines Medsafe has approved specifically for male pattern hair loss, and the evidence behind it is unusually consistent. In the original trials, finasteride halted further loss in roughly 83 to 90 percent of men, and around two thirds had visible regrowth by two years. A ten-year follow-up study found 86 percent of men had maintained or improved their hair count over the whole decade. It works best on the crown and mid-scalp, and it can hold a receding hairline, but it can't revive a follicle that has already closed. That's the case for starting early rather than waiting to see how bad it gets.
Buying finasteride from overseas websites
You'll find overseas sites offering to ship finasteride to New Zealand with no prescription. Two problems. Importing prescription medicine without a valid script is unlawful, and parcels are seized at the border. More importantly, you have no idea what's in the packet: unregulated online pharmacies are a well-documented source of counterfeit and substandard medicines. Medicine dispensed by a New Zealand pharmacy has come through a regulated supply chain, so you know what's in the bottle. With legitimate online prescribing now available in NZ at a similar price, the grey-market route is risk with no upside.
Finasteride in NZ: FAQs
Do I need a prescription for finasteride in NZ?
Yes. Finasteride is prescription-only in New Zealand in tablet and topical form. A doctor has to assess you first, which can be done entirely online.
Is Propecia still available in New Zealand?
Yes. Propecia is Medsafe-approved and stocked by NZ pharmacies on prescription, alongside generic finasteride tablets at the same strength.
Can I buy Propecia or finasteride online without a prescription?
Not legally. Overseas sites that ship without a script are importing prescription medicine into NZ unlawfully, parcels can be seized at the border, and counterfeit finasteride is common. A doctor-led NZ service is the legitimate online route.
How much does finasteride cost in NZ?
Roughly $40 to $55 a month for the tablets at a pharmacy, plus whatever your GP charges for the script. Through Magna it's from $49 a month with the assessment, medicine and delivery included.
Is finasteride funded by Pharmac?
Not for hair loss. It's only subsidised for enlarged prostate, under Special Authority.
Finasteride or dutasteride?
Finasteride is the first choice for most men and has the longer safety record. Dutasteride blocks more DHT and is sometimes used when finasteride alone isn't enough. Here's the full comparison.
How quickly can I start?
The Magna assessment takes about three minutes, and most men have their call with a Magna team member within a day or two and their first delivery within a week.
Can women take finasteride?
Not if they are or could become pregnant. Women with hair loss have other options, including minoxidil, and should be assessed by a doctor.
The bottom line
Finasteride is prescription-only in New Zealand, unfunded, and the same medicine whether the box says Propecia or not. The difference between routes is convenience and what you pay around the tablets, not the tablets themselves. If you'd rather skip the waiting room, start your online assessment, a New Zealand-registered doctor will review it, and you'll have a call with a Magna team member to confirm the right plan.
Finasteride is a prescription medicine. Treatment is subject to assessment and approval by a New Zealand-registered doctor, and individual results vary. Ask your doctor whether treatment is right for you.
