Exchange and cross rates are quoted against one New Zealand dollar.
The TWI is a weighted average of the New Zealand dollar with the currencies of New Zealand's major trading partners. We publish the following TWIs:
Daily and monthly.
We release data on a same-day basis at 3:00pm. We update real TWI estimates monthly once relevant data is available.
The statistics release calendar provides a long-term plan of scheduled releases. We update and release the calendar on the first working day of the month.

Although there is no legal requirement for us to publish data on exchange rates, we disseminate the data as a service to the public.
The latest data added to the table are in bold font. Normally there are no revisions to these data as we collect them directly from the market. However, if revisions are necessary, they will also be in bold font. This applies to the summary table only and not Excel files. Any major changes will be accompanied by a note.
The exchange rate is the rate at which one currency is exchanged for another currency.
This is the exchange rate relationship between two currencies based on each other’s relationship with a third, typically the US dollar.
Financial institutions trading financial instruments will normally quote both bid and offer rates for those financial instruments. The mid-rate is the rate in the middle of this range.
The euro (currency code EUR) replaced the national currencies of certain members of the European Union on 1 January 1999. Until 31 December 1998, we collected the NZD/DEM (Deutsche mark). From 5 January 1999 (the first banking day in 1999), we started to collect the NZD/EUR. Note that the euro replaced the Deutsche mark as a TWI contributor on 5 January 1999. The official fixing rate (OFR) for converting the Deutsche mark to the euro is 1.95583.
The 14:00 reference rate for the New Zealand dollar is the result of cooperation between the New Zealand Financial Markets Association (NZFMA), World Markets (WM) Company and Refinitiv. The reference rates are referred to as the ‘WM/Refinitiv New Zealand Dollar Fixes 14:00’, and are calculated using an internationally accepted methodology.

The trade weighted index (TWI) is a measure of the value of the New Zealand dollar (NZD) relative to the currencies of New Zealand's major trading partners. The TWI is our preferred summary measure for capturing the medium-term effect of exchange rate changes on New Zealand’s economy and inflation. The TWI ‘basket’ of currencies includes 17 of New Zealand's most significant trading partners.
The TWI is weighted using bilateral trade in merchandise and services. We have backdated the TWI to January 1984 using a consistent methodology.
We calculate the nominal TWI on a daily basis and rebase it to equal the value of the TWI on 31 October 2014 using the old methodology.
We calculate the real TWI on a monthly basis and rebase it to the monthly average of the TWI in October 2014 (old basis). The official real TWI started in 1984. An analytical real TWI starting in 1970 is available in the exchange rate key graph. In 2016, we incorporated several changes to the real TWI.

The historical TWI is ‘as published’ on the day using the method that existed at the time. The method used to construct the official TWI has changed several times:
The historical TWI starts from July 1986.
