SIM cards & keeping a number

New Zealand has no prepaid SIM registration law, so buying and activating a SIM generally needs no ID (per GSMA and other industry summaries; no government text was found, and some shops may still ask).

Keeping a number is cheap — one top-up a year: Skinny officially requires a top-up at least every 12 months, 2degrees at least NZ$10 every 365 days. The widely quoted “a NZ$1 transfer from another Skinny user also counts” has no official source and has been removed.

Skinny

Number-keeping SIM

Network: A Spark brand on the Spark network
Price: SIM price varies; plans from NZ$13 per 4 weeks, or just top up without a plan
Keeping the number: Skinny help article “Inactive SIM - No top up within 12 months” and terms (the site loads text via script and the help site didn’t resolve from here — per search excerpts): top up at least once every 12 months. After 12 months with no top-up the number goes inactive (emergency calls only); top up NZ$5 or more within 30 days to restore it. After more than 1 month inactive the number is permanently deleted and credit expires. Warning texts 1 month, 1 week and 1 day before
ID check: No ID needed (no prepaid registration law in New Zealand)
SMS & calls: A normal NZ number. Official roaming page: roaming packs are available in China (3 days NZ$11 with 100 min / 100 texts / 500MB), and pack allowances cover incoming and outgoing calls and texts; the cost of receiving texts in China without a pack wasn’t verified. From July 2026 a VoLTE-capable phone is needed for calls while roaming in China; new SIMs must be activated in New Zealand before adding a roaming pack

Pros

One NZ$5 top-up every 12 months keeps it
Three warning texts before expiry

Watch out

Number is permanently deleted 1 month after going inactive
The official keep-number text couldn’t be opened directly; based on search excerpts
New SIMs must be activated in New Zealand first

2degrees Prepay / eSIM

Number-keeping SIM

Network: 2degrees’ own network (MNO)
Price: SIM price varies; minimum top-up NZ$10; the online shop only ships to physical NZ addresses
Keeping the number: 2degrees help: top up at least NZ$10 every 365 days; each top-up is valid for 365 days. Otherwise unused balance is forfeited and the SIM expires. How long the number is kept after the SIM expires isn’t stated
ID check: No ID needed (no prepaid registration law in New Zealand)
SMS & calls: A normal NZ number. Official roaming page: China is a Daily Roaming destination at NZ$8/day, charged on any day you make or receive a call (including voicemail diversion), send a text or use data; receiving a text is not in the help page’s list of triggers. Prepay needs an active plan to roam

Pros

NZ$10 a year keeps it
Just receiving texts in China doesn’t trigger the NZ$8 daily charge (per the official list of triggers)

Watch out

How long the number is kept after expiry isn’t stated
Answering a single call in China costs NZ$8 for the day
