Getting a SIM Card and Mobile Plan in New Zealand: What Australians Should Expect

Getting connected is one of the first things to sort when you land in New Zealand. Here's how the three main networks compare for a new arrival from Australia, based on their own published pricing as at 26 August 2026.

Your first 24 to 48 hours

1. 1

   Keep your Australian SIM for the first few hours

   It'll roam on arrival, which is fine for a quick message or a rideshare booking, but roaming charges add up fast. Treat it as a stopgap, not a plan.

2. 2

   Grab a prepaid SIM at the airport or a nearby store

   One NZ, Spark and 2degrees all have retail presence at the main airports and in most shopping centres and supermarkets.

3. 3

   Use prepaid as a bridge while you sort an address

   Prepaid gets you connected immediately without a contract or credit check, which is useful while you're still deciding on a longer-term plan.

The three networks

New Zealand has three mobile networks: Spark, One NZ (formerly Vodafone NZ) and 2degrees. All three offer prepaid SIMs with no contract, and pricing is generally lower than Australia's big three for comparable data, though plan structures differ enough that a direct dollar-for-dollar comparison isn't straightforward.

One NZ's Prepay Plus range, as published on one.nz as at 26 August 2026, starts at $10 a month for a Starter plan with 250MB of data, rising through rollover plans at $18 to $30 a month for 1 to 3GB (unused data rolls over for up to a year), up to Endless plans from $50 to $73 a month with uncapped data, and an $88 a month Unlimited plan at full speed. A SIM itself costs $2.

2degrees' Prepay range, as published on 2degrees.nz as at 26 August 2026, runs from $8 a month for 1GB up to $85 a month for unlimited data, with monthly tiers at $15 (3GB), $20 (5GB), $25 (8GB), $35 (15GB) and $60 (40GB), plus fortnightly options for shorter stays. Unused data carries over, and most plans include unlimited calls to other 2degrees numbers and unlimited texts to NZ and Australian networks.

Spark also runs prepaid plans in a similar price range, but its current plan lineup wasn't accessible to verify directly against Spark's own site at the time of writing; check spark.co.nz directly for its current pricing before comparing against One NZ and 2degrees above.

Prepaid vs postpaid

Prepaid is the easiest way to get connected in your first week, with no contract, no credit check and no NZ address required. Once you've settled into a bank account and a fixed address, a postpaid ("pay monthly") plan is usually better value if you're using more than a few GB a month, and often bundles in a phone if you need one. There's no rush to switch, since prepaid works perfectly well long-term for lighter users.

Key Takeaways

• Prepaid SIMs from One NZ, Spark or 2degrees are available at the airport and most retail stores, with no contract or NZ address required.
• One NZ's Prepay Plus starts at $10/month for light use; 2degrees starts at $8/month, both as at 26 August 2026.
• Unlimited-data prepaid plans run from roughly $85 to $88/month across the two networks confirmed here.
• Switch to a postpaid plan once you're settled if you use more than a few GB a month; it's usually better value.

Frequently Asked Questions

Can I buy a New Zealand SIM before I arrive?

Most travel and airport-focused SIMs are designed for tourists and cost more than a standard local prepaid SIM. It's usually cheaper to buy a standard prepaid SIM once you land.

Will my Australian phone work in New Zealand?

Almost certainly. New Zealand and Australia use compatible network technology, so an unlocked Australian phone will generally work fine with a local NZ SIM.

The bottom line

Grab a prepaid SIM in your first day or two, use it as a bridge while you settle, and move to whichever plan suits your actual data use once you've got a bank account and an address sorted. None of the three networks lock you in on prepaid, so switching later costs nothing but a new SIM.
