ANZ Bank's mortgage lending to people with small deposits shrank by a whopping $924 million in the June quarter.
However, its mortgage lending to people with more than a 20 percent deposit grew by an even more whopping $1.63 billion in the three months.
New Zealand's largest bank also says the strong economy, market share gains and improved productivity helped drive its profit for the nine months ended June up 21 percent to $1.24 billion.
ANZ's total mortgage book grew by $704 million to $59.2 billion in the three months ended June.
ANZ said it was now the market leader for all new home lending in all major New Zealand cities, including Auckland and Christchurch.
The bank said its gross lending since 30 September last year grew by $3.68 billion, and mortgage lending accounted for $2.63 billion of that.
Helping the profit increase, the bank wrote back $19 million in charges for bad debts in the June quarter, making the total charge for the 9 months just $20 million, down from $49 million in the same 9 months a year earlier.
