The shape of a New Zealand trip
New Zealand is two main islands plus Stewart Island and a scatter of smaller ones — about 268,000 km² total, with around 5.3 million people, most of them on the North Island. The travel pattern usually splits the same way: Auckland and the Coromandel for North Island culture and beaches, Wellington for the capital and ferry, then the South Island for the scenery — Marlborough, Kaikoura, Christchurch, Aoraki, Queenstown, Fiordland. The cell network covers the populated coasts and main highways densely; the deep interior — Fiordland, the Southern Alps, Stewart Island — is a different reality.
Roamzy charges $1.54 per gigabyte in New Zealand. That's $0.0015 per megabyte, billed in real time on Kiwi networks. No subscription, no expiry on the unused balance, no minimum bundle. One per-MB rate across 193 countries — same rate in Auckland as on the road around Lake Tekapo.
How much will Roamzy actually cost on this trip?
A typical New Zealand day uses 0.8–1.5 GB: Maps for SH1 and the back-country roads, the Metlink and AT apps for transit, your bank app for the universally contactless payments, the camera-translator on Māori place-name signage (often dual-language), the InterIslander ferry app, video calls home. Call it 1 GB/day:
| Trip length | Roamzy ($1.54/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days (Auckland) | $4.61 | $15–40 | $15–30 + paperwork |
| 2 weeks (both islands) | $21.50 | $60–140 (often two passes) | $25–45 + 30-day cap |
| 4 weeks (campervan loop) | $43.01 | $120–280 (multiple passes) | $30–55 + 30-day cap or two SIMs |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A SIM at AKL or WLG is sold from the standard kiosks. The tariff is fine; the queue after a 12-hour flight from anywhere isn't. The eSIM is attached during taxi; the meter starts on a Kiwi tower.
How is coverage distributed by region?
| Region | 5G | LTE | Notes |
|---|---|---|---|
| Auckland, Wellington, Christchurch, Hamilton, Tauranga | Yes | 100% | 5G dense; LTE on the rail and ferry approaches |
| SH1 (Auckland–Wellington–Picton–Christchurch) | At population centers | Most of the route | Brief drops on the Desert Road and the Kaikoura coast |
| Coromandel, Bay of Plenty, Hawke's Bay | In towns | Solid | Dense in the resort zones |
| Queenstown, Wanaka, Te Anau | Yes in town | Reliable | Solid in the towns; weakening on the back roads to glaciers and lakes |
| Fiordland, Westland, the Southern Alps | No | Patchy | Milford Sound road has known dead zones; the West Coast in stretches |
| Stewart Island, the Catlins, the far East Cape | No | Light to none | Plan offline |
Free Wi-Fi is widespread in cafés, libraries, and i-Sites. Throughput varies; the eSIM is what you want once you're 50 m past the door.
Things you'll feel about New Zealand specifically
- Cashless is the default. Visa/Mastercard contactless and Apple/Google Pay work in supermarkets, pubs, parking machines, even small backcountry cafés. You'll need data for the bank-app push to confirm.
- The InterIslander and Bluebridge ferries have onboard Wi-Fi but it's variable; cellular drops mid-Strait for stretches.
- DOC track passes and hut bookings are app-based — Great Walks bookings, Sounds water taxis, the lot.
- Mountain weather changes fast. The MetService app and DOC alerts are the practical ones to have on hand.
- The Desert Road and the road to Milford Sound have famously thin coverage. Pre-download navigation.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type I | 230 V | 50 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Your first eSIM is free and comes with real data on us. After that, top up from $20 in stablecoins (USDT or USDC): no cards, no banks, no FX surcharges
- The QR code appears in your dashboard as soon as the eSIM is issued
- On the iPhone itself (iOS 17.4 or newer), tap Tap to install in the QR card; otherwise Settings → Cellular → Add eSIM → scan QR (do this on home Wi-Fi before you fly)
- The counter starts the moment you land at AKL, WLG, CHC, or ZQN
Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have, because they were never built in.
- No welcome promo that bait-and-switches the second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth both cost $0.0015/MB.
- No auto-renewal. Balance runs out, the eSIM stops. No background charge surfacing months later.
There is no plan here to pick correctly, so there is no plan to pick wrong. New Zealand runs on a meter because a meter needed the least fine print of anything we could build.
What if my trip continues to other countries?
New Zealand pairs naturally with the Pacific and Asia. The eSIM hands over the moment you cross:
- Thailand — common stopover via Singapore or Hong Kong
- Japan — direct from AKL to Narita
