Technical Due Diligence & Mobile Architecture Consultancy for New Zealand SMBs
Before committing $40,000 to $80,000 NZD to external agency retainers for dual native mobile apps, New Zealand boards and technical founders use our 4-stage Architectural Audit to verify whether a single TypeScript PWA and Edge API stack satisfies 100% of operational requirements.
Vendor Quote Deconstruction & Store Risk Review
We evaluate agency proposals line-by-line against W3C Web Capabilities, Apple App Store Review Guidelines (including §3.1.1 in-app purchase enforcement and §4.2 minimum functionality), and New Zealand Privacy Act 2020 data sovereignty rules.
In over 75% of New Zealand SMB scoping reviews conducted since 2017, features pitched as "requiring custom Swift and Kotlin native development" — such as camera barcode scanning, biometric login, offline forms, and push notifications — are natively supported by modern Safari WebKit and Android Chrome engines at one-third of the capital cost.
Generate Free Project Brief →Legacy Monolith to Edge PWA Refactoring
Whether transitioning from an ageing Cordova/Ionic wrapper, an expensive dual-native build, or a heavy client-side builder, we design zero-downtime URL mapping (preserving 100% of historical backlinks) and Service Worker caching topologies.
Our refactoring blueprint separates presentation from business logic: deploying an immutable HTML5/TypeScript frontend to Auckland and Sydney Anycast edge nodes while connecting to existing Xero, Vend/Lightspeed, MYOB, or custom PostgreSQL backends via authenticated REST/GraphQL endpoints.
Review 24/36-Month TCO Models →Five Architectural Questions to Ask Before Signing an App Development Contract in New Zealand
Use this governance matrix during vendor selection meetings in Auckland, Wellington, or Christchurch to protect your organisation from proprietary lock-in and unexpected App Store rejection cycles:
| Due Diligence Question | Red Flag Agency Answer | Best-Practice 2026 Engineering Standard |
|---|---|---|
| 1. Do we own the raw source code and domain routing from Day 1? | Proprietary locked builder with mandatory monthly licence to view code | Full Git repository ownership, open W3C standards, portable Docker/Edge deploy |
| 2. Will Apple §3.1.1 take 15%–30% of our customer payments? | "We will figure out App Review after we build the native binary" | Pre-launch regulatory classification; browser PWA checkout for digital services |
| 3. What happens when iOS 19 or Android 16 ships next year? | $12,000+ NZD mandatory annual rebuild retainer | Standards-based Web App Manifest & Service Worker requiring zero binary re-compile |
| 4. How fast will the first screen load on rural NZ cellular? | 180 MB+ download before the user sees a login screen | Sub-1.5 MB Brotli shell with Largest Contentful Paint under 1.8 seconds |
| 5. Where is customer data processed under NZ Privacy Act 2020? | Unverified third-party analytics SDKs siphon user telemetry | Client-side computation + first-party cookieless telemetry under IPP 1–13 |
| 6. How are offline rural workflows and ferry drop-outs handled? | App freezes or loses form state whenever cellular signal drops | Workbox Service Worker + IndexedDB queue with automatic background sync |
