Web app development for New Zealand businesses

What Kiwi businesses build as web apps

A web app is a site people log in to and use, not only read. In New Zealand the common cases are customer portals for trades and professional services, booking and scheduling tools for clinics and tourism operators, job and quote management for contractors, member systems for clubs and associations, and software products for sale overseas. The small market means many founders plan from day one for Australian and international customers as well.

If you are testing an idea, a narrow first version is cheaper and teaches more. Our SaaS MVP cost guide shows what a first release usually contains, and the web app development service page lists the full scope.

Stack and hosting choices

We prefer plain, widely used tools over fashionable ones. That keeps hosting costs low and leaves you free to move to another developer without a rewrite. See Next.js vs WordPress if you are weighing a custom app against a CMS.

Privacy Act 2020 and app design

A web app stores personal information by design, so the Privacy Act 2020 shapes the data model. We collect only what each feature needs, set retention periods, give users a way to see and correct their data and log who accessed what. Passwords are hashed, sessions expire and admin accounts use two-factor login.

• Information privacy principle 12 covers disclosure of personal information outside New Zealand. Cloud hosting, email providers and our own team in India are part of that map, so we document them. Ask your lawyer to confirm what applies.
• A breach that is likely to cause serious harm may need to be reported to the Privacy Commissioner and affected people. We agree an incident plan before launch.
• Staff and customer roles are separated, and each role sees only what it needs.
• Backups are encrypted and restore tests are run, not assumed.

If the app handles health, children's or financial information, extra care and legal advice are sensible. We flag these cases on the first call.

Consumer and marketing rules inside the app

Prices, offers and delivery promises shown in an app fall under the Fair Trading Act 1986, which the Commerce Commission enforces. Subscriptions should make renewal terms and cancellation clear. For consumer sales, the CGA, a 1993 consumer-rights statute, gives buyers automatic rights, so terms of sale should not claim less. We build the pages and emails, and your lawyer approves the wording.

Prices should be shown including 15% GST for consumer sales, with a clear note when business customers see figures excluding GST. Invoices that go to Xero carry the right tax codes after testing with sample data.

How a build runs

1. ScopeUser roles, core workflows and what is left out of version one.
2. DesignClickable screens that staff and customers can try before any code.
3. Build in sprintsWorking releases to a staging address every one to two weeks.
4. TestAutomated tests, manual checks on real devices and a security review.
5. Launch and careMonitoring, backups and a monthly plan for fixes and small changes.

New Zealand is 6.5 hours ahead of India in winter and 7.5 hours ahead in daylight saving. A 3 pm demo in Christchurch is early morning in Pune. We work remotely and have no New Zealand office.

Cost

Projects start at $1,500 and our rate is $30 an hour, in US dollars. The quote reflects the number of screens, roles, integrations, reports and data migrations. Read the web app cost guide for the main drivers. Cloud hosting and third-party fees are paid by you directly. Ask your accountant how GST applies to services bought from an overseas supplier.
