Exiting BNZ boss Anthony Healy saw a 16 per cent jump in his pay packet this year, pushing his total remuneration to over $3 million.
The move comes as the bank has been cutting staff with up to 100 jobs expected to go, mainly at its head office in Auckland.
Healy who will leave the top job in New Zealand and head back to parent company National Australia Bank in January, saw his remuneration increase from A$2.38m ($2.64m) in 2016 to A$2.77m ($3.07m) in the year to September 30, 2017.
At the same time the BNZ increased its net profit by 2.6 per cent $937 million and its cash earnings rose 7.9 per cent to $983 million.
But Tali Williams, secretary retail, finance and commerce division for First Union, said Healy's increase was inappropriate given some BNZ staff were facing job losses or a reduction in hours.
