Where to Get Topical Finasteride in NZ
The short answer: topical finasteride is a prescription medicine in New Zealand, and it isn't sold as a ready-made product. It's made to order against a script. You can't buy it over the counter, and you can't order it without a prescription. The realistic ways to get it are through a GP or hair loss doctor who writes a compounded prescription, or through an online doctor-led service like Magna that handles the prescription, the compounding and the delivery in one go.
Why you can't just buy it
Two reasons.
First, finasteride is prescription-only in NZ in any form. Oral or topical, it needs a doctor's assessment and a script.
Second, there's no Medsafe-registered topical finasteride product on New Zealand shelves. Unlike minoxidil, which you can pick up as Regaine at strengths up to 5%, topical finasteride only exists here as a compounded medicine a pharmacy makes it up specifically for you, to the strength and combination your doctor prescribes. That's why you won't find it at Chemist Warehouse, and why "buy topical finasteride NZ" searches mostly lead to overseas sites that can't legally ship it here.
What topical finasteride in NZ actually looks like
Because it's compounded, it's rarely finasteride on its own. Most NZ prescriptions combine it with minoxidil in a single solution commonly finasteride 0.1% or 0.25% with minoxidil 5% to 7%, sometimes with a small amount of retinoic acid to help it absorb. One bottle, one application, two mechanisms: finasteride blocking DHT at the scalp, minoxidil stimulating the follicle.
It's applied once or twice a day to the scalp, and a 100ml bottle usually lasts around three months.
The three ways to get it
1. Through your GP
Your GP can prescribe topical finasteride, but a few things get in the way. Compounded medicines aren't standard GP territory; most GPs are more familiar with the oral tablet, and writing a compounded script means specifying the strength and combination and knowing which pharmacy will make it. You then need to get the script to a compounding pharmacy (there are only a handful in NZ), arrange collection or courier, and go back for a new script when it runs out. It works, but you're doing the coordinating yourself, and every follow-up is another appointment.
2. Through a dermatologist or hair loss clinic
A dermatologist or specialist hair clinic will know compounded topicals well and can tailor the formulation properly. The trade-off is access and cost: private specialist appointments in NZ typically run $250 to $400 for a first visit, waitlists can be long outside the main centres, and you're still sourcing and re-ordering the product yourself between visits.
3. Through an online doctor-led service
This is the route most men end up on, because it removes the coordinating. With Magna, you complete a short online assessment, a New Zealand-registered doctor reviews it and calls you, and if topical finasteride is the right option, they prescribe it. The prescription is compounded in New Zealand, the bottle is delivered free to your door in plain packaging, and follow-ups and adjustments are included. Plans start from $49 a month.
The doctors who review Magna assessments work with hair loss every day, which matters with topicals - getting the strength and combination right for your stage is what determines whether it works.
What it costs
Sourcing it yourself: a compounded finasteride and minoxidil solution from a NZ pharmacy typically runs around $70 to $90 a month for the medicine alone, plus the GP or specialist visit to get the script, plus courier if you're not collecting.
Through Magna: from $49 a month, with the doctor's assessment, the consultation, the medicine, delivery and ongoing follow-ups all included.

Who topical finasteride suits
The main reason men choose topical over oral is side effects. Applied to the scalp, far less finasteride reaches your bloodstream. In the phase III trial of a topical finasteride spray, serum DHT dropped by around 34% on topical compared with roughly 56% on the oral tablet - a similar effect where it counts, at the scalp, with lower systemic exposure.
That makes it a good fit if you:
- want the DHT-blocking effect of finasteride but are wary of oral side effects
- have been told oral finasteride isn't right for you
- are already using minoxidil and want to add finasteride without taking a second medicine
It's not for everyone. Topical still delivers some finasteride systemically, so it isn't a side-effect-free option, and it needs to go on every day to work. And it's not suitable for women who are or could become pregnant as finasteride can cause birth defects, which is why Magna doesn't prescribe it for women of childbearing age.

How long until it works
Same as oral: expect three to six months before you see change, with the best results at twelve months and beyond. Some men notice extra shedding in the first couple of months as weaker hairs make way for new growth but that's normal, and it settles.
