Phone numbers in New Zealand

The numbering plan for New Zealand

Every phone lookup starts from the numbering metadata: it settles whether a number is valid for New Zealand, how it is written nationally and internationally, and which line type its range belongs to. The example numbers below are the plan’s own examples per line type, not real subscribers.

The regulator table behind a lookup here

NAD number register (New Zealand) (synced 2026-09-07, table version 2026-09-07). The table is partial: the regulator publishes only part of its plan in machine-readable form, so absence from it says nothing about a number and block_status stays null outside it. A lookup names the block holder as carrier with carrier_source block_allocation — the original allocation, never who serves the number today.

• 9,673 blocks in the table: 5,051 allocated, 4,586 unassigned, 36 reserved.
• 52.2 % of the blocks are allocated.
• 99.9 % of allocated blocks name a holder.
• 12.7 % of allocated blocks settle the line type on their own (0 mobile, 640 VoIP).

Measured weekly (last on 2026-09-06) from the table itself. These are shares of the regulator’s own table, not of real traffic, and they say nothing about who serves any one number today.

What a lookup answers for a number here

Every number the plan accepts for New Zealand comes back with its formats, its line_type and line_type_source, its region and timezones, and the is_fictional and is_disposable flags from the bundled fiction ranges and the synced list of SMS-receiving numbers. Because NAD number register (New Zealand) covers New Zealand, a lookup also answers carrier from the block holder and block_status where the partial table has the block.

Pacific/Auckland: the whole country keeps one clock, so a lookup answers that zone for every number here.
