Trust Bank New Zealand Ltd was a registered bank that operated in New Zealand between 1986 and 1996. It was made up of (most of) the former regional savings banks that had their origins as far back as 1847. It was acquired by Westpac Bank in 1996 which phased out the Trust Bank brand at the end of 2002, when the bank was rebranded from WestpacTrust to simply Westpac.
