BNZ employees will now be getting six weeks annual leave, the company announced in its full-year results.
The company told employees about the move on Wednesday, saying annual leave will be increased from four to six weeks a year.
Chief executive Angie Mentis said in a statement that the increase will come into effect from January 1, 2020.

Mentis said the move means its employees can work "in a way that best suits them.''
"We can empower them to grow and lead more balanced lives."
More leave, extended parental leave and flexible work hours is in "keeping with our focus on wellbeing", Mentis said.
"We want to support our people to do their best work for our customers."
By law, any New Zealand employee is entitled to four weeks annual leave each year when they have worked for a company for 12 months.
"The right to four weeks annual holidays per year applies to all types of employees," Employment New Zealand says.
"In limited circumstances, some employees may be paid their annual holiday entitlement on a pay-as-you-go basis."
