Jon Hartley has been appointed to chair Kiwibank after current chair Dr Susan Macken said she would not stand for reappointment.
Macken's term will end on November 28 when Hartley will step into the role.
She was appointed to the Kiwibank Board as an independent director for a three-year term in November 2016 and became Chair in April 2017.
Macken said she had decided not to seek reappointment after reflecting on the changing nature of the governance requirements for the bank as it evolved.
"I decided Kiwibank would best benefit from a chair with the specific skills to lead them in this new chapter, and informed shareholders and the board last month I would not be seeking reappointment.
