By the 1970s, New Zealand's telephone network consisted primarily of step-by-step telephone exchanges or, in the main centres, a mixture of rotary and step-by-step exchanges, with a few rural areas still served by manual exchanges. Local telephone number lengths varied from 3 to 6 digits depending on the size of exchange and population of the local calling area. Local numbers started with digits 2 through 8; numbers starting with 9 were not assigned due to easily being misdialed under pulse dialling, while 0 was for calling the operator and numbers beginning with 1 were for special services (e.g. emergency services on 111).[1]
Numerous complex dialling instructions appeared in the front of telephone books explaining the number sequences needed to reach 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 metres in some step-by-step local exchanges. Local calls were free (and still are for residential customers). Long distance (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).
Crossbar exchanges were installed from the 1970s, and electronic exchanges from 1982.
Subscriber toll dialling (the historical codes)
Subscriber toll dialling (STD) was introduced in the New Zealand telephone network in the mid-to-late 1970s, a result of the introduction of NEC crossbar-based toll exchanges and their ability to perform number translation. Upper Hutt was the first exchange to implement STD, on 9 April 1976.[2] 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. A complete list of STD codes from 1987 is below:

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, as exchanges often increased the length of local numbers to accommodate new lines.
Reorganisation
With the introduction of NEC stored program control exchanges in 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, local telephone numbers were standardised to seven digits. In many parts of the country, the old area code was incorporated into the new number, however in some areas the numbers changed completely.

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 a seven-digit local number, of which the first three digits generally specify the exchange and the final four specify the subscriber's unique line at that exchange.
International number lengths
The long-distance trunk prefix, 0, which is prepended to national numbers, is not part of the international number.
The minimum number length after the international prefix is three digits. Most numbers, other than service numbers have at least eight digits.
The maximum number length after the international prefix is nine or ten digits (depending on provider).
Present numbering plan
New Zealand follows an open numbering plan. The country code is 64. The long distance dialing prefix is 0 and the international prefix is 00.
New Zealand landline phone numbers have a total of 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: 3, 4, 6, 7, and 9. These must be dialled, along with the domestic trunk prefix, 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 combined domestic trunk prefix[3] and area codes are:[4]
Telephone numbers for mobile phones begin with 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 1990s however, Telecom mobile phones could dial other Telecom mobile phones without the (then) 025 prefix, making 025 act like a landline area code.
Protected by Management Committee 30 January 2009 to preserve the potential code expansion option.
025
Unused
6 or 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 (e.g. 027-4xx-xxxx). Telecom told existing 025 subscribers that their new number was simply their old number with '0274' in front.[citation needed] While technically correct, it is misleading and has resulted in numbers being incorrectly shown in advertising as "0274 xxx xxx". "0274" is not a valid dialling code.
0260
Formerly Team Talk
This Code Block is active and in use but is marked "Unallocatable" as Teamtalk is not a current member of the NAD; this does not impact routing. This Code Block is not subject to LMNP.
This Code Block was allocated to Two Degrees Mobile in exchange for 0266 on 17 July 2015, Warehouse Mobile launched on 28 November 2015 as an MVNO on 2degrees Mobile
One NZ (formerly Vodafone New Zealand) acquired TelstraClear in 2012.
The introduction of mobile number portability on 1 April 2007 meant that an increasing number of mobiles would be operating on a different network from 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 2degrees. A reply will be sent to verify whether the number is operating on their network or not. As of September 2019[update], this service will work for Vodafone and Spark Active.
Other numbers
Toll-free and premium-rate calls
Toll-free numbers begin with 0508 or 0800,[4] followed by usually six but sometimes seven digits.
Premium-rate services use the code 0900 followed by five digits (some with six digits).
Local-rate numbers, such as Internet access numbers, have the prefix 08xx, and are usually followed by five digits.
0508 Tollfree sold by many network operators (originally launched by Clear Communications as a competitor to the then Telecom-only 0800 range)
0800 Tollfree sold by many network operators (originally only available to Telecom NZ, now known as Spark)
Text message numbers for mobile phones are 3 or 4 digits long.
