Westpac has retained the lucrative contract for the bulk of the Government's banking services.
The Australian-owned bank became banker to the Government in 1989.
It has now kept that position after the tender was put up for the first time in more than two decades.
Finance Minister Bill English announced today that Westpac had won the eight year contract to provide the Crown transactional banking services.
The decision comes after the Green Party agitated for years to have the banking services put to tender, in a bid to have the Government's banking done by a New Zealand bank.
