Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

You keep your number when you switch (LMNP). The Commerce Commission treats it as a regulated service and its 2021 determination extended that for another five years, so a range only tells you who first issued the number, not whose network it is on today.

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).

Read more

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
