Best Personal Trainer Software in New Zealand (2026 Comparison)

Most "best personal trainer software" lists are written for the American market and quietly assume you are one too. That is fine until you try to send a GST invoice, or watch your subscription cost move because the New Zealand dollar did.

This is the New Zealand version. Same honest structure as our Australian comparison, different facts, because the tax, the currency and the food data are all different on this side of the Tasman.

Start with the job, not the software

Coaches usually arrive at a comparison table with one of two problems, and they need quite different tools.

Problem one: programming admin. You are writing plans in spreadsheets, texting PDFs, and losing track of what a client did three weeks ago. You want a program builder, an exercise library with video, and an app your client will actually open.

Problem two: business admin. You are chasing payments, writing invoices by hand, juggling bookings and cancellations in your phone's calendar, and working out GST at the end of the quarter.

Most of this comparison is about problem two, because that is where the money and the tax live and where New Zealand coaches get the worst of the global platforms. Problem one has cheaper answers, including a free one covered further down. Deciding which problem is actually yours saves you a fortnight of trials.

The global platforms, compared against each other

For New Zealand coaches the practical shortlist is smaller than the review sites suggest, because most of these platforms treat NZ as an afterthought rather than a market.

Trainerize (owned by ABC Fitness) is the most recognised name and has the deepest integrations. The free tier covers one client, then plans scale by roster: roughly NZ$17 to NZ$38/mo for 2 to 5 clients, about NZ$121/mo at 30 clients and NZ$207/mo at 50. The headline numbers look reasonable until you notice what sits outside them, because billing, scheduling and nutrition are each separate add-ons. Its AI workout builder is a recent addition to a platform designed before AI was a consideration.

TrueCoach is the strength-coach favourite for one-to-one remote delivery: clean interface, intuitive builder, and it does not pretend to be everything else. Roughly NZ$52/mo for 5 clients, NZ$121/mo for 20, NZ$285/mo for 50. Automated payments through Stripe are now included on all plans with no platform transaction fee, which is a genuine differentiator. Thinner on the studio and class side.

My PT Hub markets itself as all-in-one and covers a lot of ground. The catch is the tiering: the Starter plan is around NZ$69/mo for three clients, so most working coaches are really looking at Premium at about NZ$182/mo. AI check-ins are a paid add-on at roughly NZ$52/mo on top.

Mindbody has been running since 2001 and dominates the large-studio market. NZ pricing works out around NZ$156/mo per location at the Starter tier, with higher tiers requiring a sales conversation, plus marketplace fees when a client discovers you through the Mindbody app. It is built for a facility with a front desk. Solo coaches routinely find it heavier than they need.

PTminder deserves more attention from New Zealand coaches than it usually gets: it is New Zealand-based (now part of Xplor) and has served the APAC market since 2012, so it is a genuine local option built for trainers rather than for gyms. It is also one of the few that lets you pick your currency and publishes real NZD, so there is no exchange-rate guesswork: NZ$88/mo for 50 clients, NZ$143.97 for 100, NZ$233 for 200, with about 10% off annual billing. No AI tooling.

Vagaro came from the salon and spa world and expanded into fitness. Pricing is per bookable calendar, from about NZ$54/mo for one, with text marketing, storage, forms and branded apps each billed separately on top. Fine if you also run treatments; a lot of surface area if you only coach.

Between them the differences are real but incremental: how good the app is, how the tiers cut, how much a marketplace matters to you, whether you need a front desk. Compare them on those terms and you will pick a reasonable one.

Pricing comparison, in New Zealand dollars

BuildStability publishes native NZD pricing, so those figures are exact: NZ$7 (Essential, 6 clients), NZ$33 (Starter, 25), NZ$99 (Pro, 100), NZ$259 (Pro+, 250). PTminder has a currency selector and publishes native NZD too, so its figures are exact as well: NZ$88 (50 clients), NZ$143.97 (100), NZ$191.05 (150), NZ$233 (200), NZ$371.04 (unlimited). All figures in this table are monthly; PTminder and several others discount annual billing by around 10%. ^† Converted from published AUD at 1 AUD = 1.21 NZD. ^‡ Converted from published USD at 1 USD = 1.73 NZD. Both are approximate 30-day average rates as of August 2026 and move daily, so treat every converted figure as indicative rather than a quote. ^§ FitPros free tier covers unlimited clients but carries a 10% platform fee on program sales, caps Power Features to a weekly quota, and excludes automations. Pro is USD $39/mo month-to-month or USD $29/mo billed annually (about NZ$67 and NZ$50^‡) and adds unlimited Power Features, automations and custom branding. It has no session booking, no client invoicing and no AI program generation. PTminder pricing shown is the 50-client plan; 100 clients is NZ$143.97/mo. Mindbody Starter is per location and higher tiers require a sales conversation. Trainerize excludes billing, scheduling and nutrition add-ons. My PT Hub Starter is limited to 3 clients. Vagaro is priced per bookable calendar with add-ons billed separately. Competitor pricing changes; verify on their own pages before deciding.

The common ground is more useful to notice. All four bill you in a foreign currency, so your monthly cost drifts with the exchange rate. None produce a New Zealand GST invoice. Most take a percentage of what your clients pay you, or route those payments through their account rather than yours.

GymMaster is the New Zealand-built option and is genuinely good at what it targets: gyms and health clubs, including 24/7 door access, readers and key fobs. If you run a facility, look at it seriously. If you are a coach with a client roster and no door to control, you would be buying a category of product you do not need. Its AI features are aimed at marketing and communications rather than writing training programs.

Where REPley by BuildStability sits, and why it is a different comparison

We are not going to claim we out-feature Mindbody on facility management or beat FitPros on price. Neither would be true, and you would find out inside a week.

The honest framing is that REPley by BuildStability was built after AI existed, for AU and NZ coaches specifically, and those two decisions change what the software is rather than how much of it there is.

Repley is the assistant, not a chatbot in the corner. Most platforms added AI to an existing product, which is why it usually sits in a sidebar and cannot touch your schedule, your billing or your client history. Repley reads real client data (injuries, RPE trends, session history, booking patterns) and acts across the whole platform. Ask it to move tomorrow's sessions to Friday and it does the shuffle. Ask for a 12-week block for a client with a cranky knee and it writes one, then checks its own structure before you see it.

Programs are checked before they reach you. Every generated program is tested against a fixed set of structural rules: that a long program reads as real training blocks rather than one week repeated, that recovery weeks are genuinely lighter, that a fat loss block actually carries conditioning, and that your equipment limits and injury flags were honoured rather than merely requested. Those checks catch structure, not suitability. They confirm conditioning is present; they do not decide whether steady rowing or hard intervals suits the client in front of you. That is coaching, and it stays yours. How we check a generated program.

Every block after the first is built from what your client actually logged. When a block finishes, End of block reads the last five sessions for each movement, including the load lifted and the effort reported, and writes the next block from those numbers. A lift that is getting harder at the same weight gets held rather than pushed.

The money side is built for New Zealand. Clients pay in NZD into your own Stripe account, not ours, and we take no commission. Invoices carry 15% GST and your GST number once you have one. Records export as CSV for your GST returns. Registration is only mandatory above NZ$60,000 of turnover in a 12-month period, so if you are under that we are not going to pretend otherwise.

Nutrition uses New Zealand food data. 7,831 New Zealand products, every one barcode-scannable, alongside 51,193 Australian ones, with NZ brands ranked first for NZ clients. Most nutrition features ship US food data, so a client scanning a product off a Countdown shelf gets nothing useful back.

Pricing is in your currency: NZ$7/mo for 6 clients, NZ$33 for 25, NZ$99 for 100, NZ$259 for 250. Every feature at every tier, including the AI. Nothing is held back for an enterprise plan.

Where Repley does not fit. We are new, and the user base is small but growing quickly. There is no marketplace to find you clients, so you bring your own. If you run a 24/7 facility with door hardware, GymMaster is the better tool. If all you need is a program builder and you like the one you have, a free tier may serve you for a long time yet, and that is a legitimate answer.

Free software: where it genuinely fits

FitPros deserves a straight answer rather than the usual dismissal. Its free tier includes unlimited clients, a full workout builder, an exercise library of over 1,000 movements with video, branded client apps on iOS, Android and web, forms and habit tracking. It launched publicly in 2025 and reports more than 10,000 coaches signed up. For a coach whose problem is programming admin, that is a serious offer.

Read the free tier properly before you build on it, though. It carries a 10% platform fee on program sales, caps its Power Features to a weekly quota, and leaves out automations. Pro removes those limits at USD $39/month month-to-month, or USD $29/month billed annually. So the real question is not free versus paid, it is whether 10% of what you sell is more or less than the subscription would have been.

It also does not do the business-admin half: no session booking, no client invoicing, no GST. Nothing about that is a criticism. It is a scope decision, and a clear one. If your clients pay you by bank transfer and you book them by text, the gap may never bother you.

The part worth understanding before you build a business on any free tier is what free actually costs to provide. Modern coaching software runs AI models, stores health information under privacy law, holds payment credentials, and needs redundancy so a Monday morning outage does not cost you a day of sessions. That is a real monthly bill for whoever runs it. Free tiers work when something funds them, and FitPros answers that question openly: a paid tier plus a percentage of program sales. The ones that have quietly disappeared over the years were usually the ones with no such engine underneath. It is worth asking any provider, us included, how the lights stay on.

A practical way to choose

1. Write down which admin is actually costing you hours. Programming or business? Be honest, because the answer sends you to different software.
2. If it is programming only, start free. Prove the workflow before you pay for anything.
3. If it is business admin, check the currency and the tax first. A platform that cannot issue a 15% GST invoice will hand that job back to you every month.
4. Ask who holds your clients' money. Your own Stripe account, or the vendor's?
5. Then compare the coaching features. They matter, but they are the easiest thing to switch later.

If you want to judge how quickly any of this moves rather than take a marketing claim on trust, our public changelog lists every release with dates. It is a fair way to compare how fast a newer tool ships against an established one.

Trans-Tasman note: if you coach in Australia, the Australian comparison covers AUD pricing, 10% GST, ABNs and BAS instead.
