Kiwibank's profit has hit a record high after strong home and business lending growth.
The state-owned bank's net profit rose 4 per cent from $126 million to $131m for the year to June 30.
Its net interest income rose from $528m to $630m but operating expenses also jumped, from $422m to $480m.
Chief executive Steve Jurkovich said the improved result was the best in the bank's 20 year history and had been driven by higher revenue and an ongoing focus on costs.
"Today's result and our continued success means $131m of profit stays right here in Aotearoa, allowing us to have even more impact for New Zealand in the year ahead as we deliver on our purpose of Kiwi making Kiwi better off."
