Exchange and cross rates are quoted against one New Zealand dollar.
The trade-weighted index (TWI) is a weighted average of the New Zealand dollar with the currencies of New Zealand's major trading partners. The Reserve Bank publishes the following TWIs:
Daily and monthly
Data are released on a same day basis at 3pm. Real TWI estimates are updated monthly once relevant data is available.
The Statistics Release Calendar provides a long-term plan of scheduled releases. It is updated and released on the first working day of the month.

Although there is no legal requirement for the Reserve Bank to publish data on exchange rates, the data are disseminated by the Reserve Bank as a service to the public.
The latest data added to the table is in bold font. Normally there are no revisions to these data as they are collected 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.
Exchange rate relationship between two currencies based on each others 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 the Reserve Bank collected the NZD/DEM (Deutsche mark). From 5 January 1999 (the first banking day in 1999) the Reserve Bank 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 for converting the Deutsche mark to the euro is 1.95583.
The 2:00pm reference rate for the New Zealand dollar is the result of co-operation between the New Zealand Financial Markets Association (NZFMA), World Markets (WM) Company and Reuters. The reference rates are referred to as the "WM/Reuters New Zealand Dollar Fixes 14:00", and is 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 the Reserve Bank's preferred summary measure for capturing the medium-term effect of exchange rate changes on the New Zealand 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. The TWI is backdated to January 1984 using a consistent methodology.
The nominal TWI is calculated on a daily basis and has been rebased to equal the value of the TWI on 31 October 2014 using the old methodology.
The real TWI is calculated on a monthly basis and has been rebased to the monthly average of the TWI in October 2014 (old basis). The official real TWI starts in 1984 but 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 (PDF 384KB).
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 in July 1986.
