The New Zealand telephone numbering plan describes the allocation of telephone numbers in New Zealand.

History

Up until the 1970's, New Zealand's telephone network consisted primarily of step-by-step telephone exchanges, or a mixture of rotary and step-by-step exchanges in the main centres. A few rural areas were still served by manual exchanges. Crossbar exchanges were installed from the 1970s, and electronic exchanges from 1982. Local telephone number lengths varied from 3 to 6 digits depending on the size of exchange and population of the local calling area.

Numerous complex dialling instructions appeared in the front of telephone books explaining the number sequences needed to dial subscribers in local "free calling" areas, and in a few cases for short distance toll calls (usually to the local city or town), which were recorded on manually read meters in some step-by-step local exchanges. Local calls were "free", and still are for residential customers. Long distance or toll calls required the manual intervention of an operator, who had access to toll circuits, either via an operator's cord board or a toll exchange (switch). Access to the toll operator was by dialling 0.

Local directory service could be accessed via 100, telephone faults via 120, and emergency services via 111.

Subscriber Toll Dialling (the historic codes)

Subscriber Toll Dialling (STD) was introduced into New Zealand telephone network in the mid 1970s, a result of the introduction of NEC crossbar based toll exchanges and their ability to perform number translation. One still needed to dial 0 to make a toll call, but instead of calling the operator, one could then dial the STD number directly. Access to the operator was via 010, while other service numbers remained unchanged.

The original STD codes were numbered roughly south to north, with a few exceptions. Some of the STD codes were:-

Town/City Historic STD Code
Whangarei 089
Auckland 09
Tauranga 075
Hamilton 071
New Plymouth 067
Palmerston North 063
Wellington 04
Nelson 054
Christchurch 03
Dunedin 024
Invercargill 021

STD codes were assigned with larger areas having short STD codes (e.g. Auckland - 09), while smaller areas had longer STD codes and shorter local numbers (e.g. Shannon - 06927). The total number length, that is STD code and local number excluding the first 0, usually totalled seven digits, but could vary up to nine, often as exchanges increased the length of local numbers to accommodate new lines.

Reorganisation

With the introduction of NEC Stored Program Control exchanges in to the New Zealand telephone network during the 1980s, and the rapid growth in demand, the breakup of the New Zealand Post Office and the creation of Telecom New Zealand, the opportunity arose to standardise local telephone numbers at 7 digits long. In many parts of the country, the old area code was incorporated into the new number, however in some areas the numbers changed completely.

Town/City Old number New number
Whangarei (089) xx-xxx (09) 43x-xxxx
New Plymouth (067) xx-xxx (06) 75x-xxxx
Dunedin (024) xxx-xxx (03) 4xx-xxxx
Invercargill (021) xx-xxx (03) 21x-xxxx

At the same time, the opportunity was taken to move directory service from 100 to 018 and charge for directory service calls. The justification for doing so was the introduction of a directory service computer system that gave access to current New Zealand telephone number listings, not just those printed in the telephone book, and the need for a separate user pays revenue stream for Telecom Directory Services, which was separate to the 5 regional (local) telephone companies, TNI and Telecom Mobile that Telecom had split itself into, as part of the sale of Telecom and deregulation of New Zealand telecommunications services.

Since 1993, land-line telephone numbers in New Zealand consist of a single-digit area code and seven-digit local numbers, the first three of which generally specify the exchange and the final four a line at that exchange.

International Number Lengths

The long distance trunk prefix, 0, that is prepended to national numbers is not part of the international number.

Minimum number length after International prefix : 3 digits (Most numbers, other than service numbers, are at least 8 digits.)

Maximum number length after International prefix : 9 digits (Except numbers starting 210 - 10 digits)

Present Numbering Plan

New Zealand follows open dialing plan.
Country Code: 64

Long Distance Prefix: 0

International Prefix: 00

Landlines

New Zealand landline phone numbers total eight digits excluding the leading 0: a one-digit area code, and a seven-digit phone number (e.g. 09 700 1234), beginning with a digit between 2 and 9 (but excluding 900, 911, and 999 due to misdial guards). There are five regional area codes: 03, 04, 06, 07, and 09. These must be dialled when calling a recipient outside the local calling area of which the caller is located. For example, one calling Dunedin from Christchurch must dial 03, even though Christchurch is 03 as well.

The area codes are:

Mobile Phones

Mobile phone numbers begin 02, followed by seven to nine digits (usually eight). The first few digits after the 02 indicate the original mobile network that issued the number.

Telephone numbers must always be dialled in full for mobile phones. In the late 1990's however, Telecom mobile phones could dial other Telecom mobile phones without the (then) 025 prefix, making 025 act like a landline area code.

Prefix Network Number length Notes
020 Orcon
021 Vodafone 6 to 8 digits 6 digits originally assigned to on plan accounts only and 7 digits assigned to prepay account customers only
022 2degrees 7 digits 2degrees was launched in August 2009.
023 Unused Owned by TelstraClear
024 Unused Protected by Management Committee 30.01.09 to preserve the potential code expansion option.
025 Unused 6-7 digits Was used by Telecom New Zealand until it was shut down on 31 March 2007. All numbers have now migrated to 027 (7-digit), with older 025 numbers prefixed with 4 (eg. 027-4xxx-xxx).
026 Telecom New Zealand, Team Talk 7 digits Used for calling Fleetlink or other trunked radios from a phone line
027 Telecom New Zealand 7 digits
028 0 Compass Communications
028 CallPlus or BLACK + WHITE
028 3 Teletraders MVNO
028 85 M2 MVNO
028 96 Airnet NZ Ltd
029 TelstraClear

The introduction of mobile number portability on 1 April 2007 meant that an increasing number of mobiles will be operating on a different network to that which originally assigned the number. To find out whether a particular number belongs to a specific network provider, one can text the mobile number of interest to 300. It is a free service provided by Telecom, Vodafone and 2degrees. Reply will be sent to verify whether the number is operating on their network or not.

Other Numbers

Toll-free and Premium-rate

Toll-free numbers begin with 0508 or 0800, usually followed by 6 digits (some numbers on 0800 have seven digits). Premium rate services use the code 0900 followed by 5 digits. Local rate numbers, such as internet access numbers, have the prefix 08xx, and are usually followed by 5 digits.

  • 0508 TelstraClear Tollfree
  • 0800 Telecom, TelstraClear and other network operators Tollfree
  • 08xy Various non-geographic services
  • 083210 Call Minder answerphone service
  • 08322 Infocall numbers

Numbers beginning with 01 are for operator services.

  • 010 National Operator
  • 0170 International Operator
  • 0172 International Directory Service

  • 11x Not allocatable. Used internally for specific emergency services.

  • *555 Traffic Safety Services (Police non-emergency traffic calls)

Text message numbers for mobile phones are 3 or 4 digits long.

Other useful numbers

  • 07 832 0000 - automated information (free call) who your toll provider is.
  • 1956 - reads back number you are currently calling from (includes the area code 03 7654321)
  • 1957 - reads back the number you are currently calling from (without the area code eg 7654321)
  • 083201234 - reads back the pilot number of the line you are calling from (if calling from a business line in a stepping group) or the individual number on the Telstra network.
  • 083201231 - reads back the pilot number as above, with area code
  • 083201232 - returns the DTMF tones of the line you are calling from
  • 137 - ringer test (ringback number); when dialled you can select that after you hang up it will call back to test your line rings

Fictional numbers

New Zealand has no dedicated series of fictional telephone numbers. Television shows and movies generally use any available range of numbers (e.g. the TVNZ soap opera Shortland Street uses the unassigned (09) 4299 number range.).
