Holafly sells only unlimited plans for New Zealand, so it has no price in the GB rows; its 7-day plan is in the week table below.
A week of unlimited data in New Zealand
| Provider | 7 days | What you get |
|---|---|---|
| ONE eSIM | $16.17 | 1 GB a day at full speed, then 512 Kbps until the next day (7 × $2.31) |
| Airalo | $27.00 | 3 GB a day at full speed, then 1 Mbps (fair use) |
| Holafly | $27.50 | No daily cap; fair use may slow very heavy use |
| Saily | – | No 7-day unlimited plan |
| Nomad | $25.00 | 2 GB a day at full speed, then 1 Mbps |
For a week, ONE eSIM's 1 GB a day plan is the cheapest way to stay online all day at $16.17. The cheapest of the others is Nomad at $25.00, which gives more full-speed data a day; compare by how much you use a day, not by the word unlimited.
Networks and coverage in New Zealand
ONE eSIM's New Zealand plans run on the One NZ network, with 5G available and 3G/4G coverage more widely. Rural and mountain areas, especially on the South Island's West Coast and parts of Fiordland, can have weaker signal regardless of provider, so plan ahead if your route includes remote tramping or driving.
Which eSIM should you choose for New Zealand?
- Short trip, light use (up to 3 GB): ONE eSIM's 3 GB plan at $6.90 (15 days), the cheapest at that size.
- Two weeks or more (5 to 10 GB): Nomad at $18.00 (30 days) is the cheapest at 10 GB.
- Heavy use (20 GB): Nomad at $28.00 (30 days) is the cheapest at 20 GB.
- Streaming or video calls every day: compare the unlimited plans above by how much full-speed data each gives a day.
How to set up your New Zealand eSIM
- Check your phone supports eSIM and is carrier-unlocked before you buy.
- Buy and install the eSIM on Wi-Fi before you fly, so the QR code or install link is already set up.
- Turn on the eSIM line and data roaming once you land in New Zealand, to avoid wasting data at home.
New Zealand eSIM FAQ
- Do I need an eSIM for New Zealand? No, but it is usually quicker to activate than buying a physical SIM on arrival, and you can set it up before you fly.
- Which is the cheapest eSIM for New Zealand at 1 GB, 3 GB or 5 GB? Based on prices checked 27 October 2026, ONE eSIM is the cheapest at each of these sizes, with validity as long as or longer than Airalo's plans at the same size.
- How long does ONE eSIM's 5 GB New Zealand plan last? 30 days, the longest validity we found for 5 GB among the providers compared here.

- Can I still use my home number with an eSIM in New Zealand? Yes, these are data-only eSIMs that run alongside your regular SIM, so calls and texts on your usual number still work.
How we check prices
We read each provider's public New Zealand page on 27 October 2026 and took its cheapest plan at or above each size, in US dollars before any coupon, with the validity in brackets; ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month and keep the date on the page and in the short answer. If a number is out of date, write to support@oneesim.app and we will correct it.
