Bank of New Zealand has sharply reduced its mortgage lending to people with small deposits in the three months to September.
However, its total mortgage lending also more than halved compared with the June quarter.
BNZ, which is owned by National Australia Bank, is the last of the major banks to lodge its September quarter accounts.
BNZ's total mortgage lending fell to $170 million in the three months ended September compared with $371 million in the June quarter.
The bank's lending to people with less than a 20% deposit plunged from $174 million in the June quarter to just $49 million for the September quarter.
That represents nearly 29% of its total new mortgage lending for the latest quarter, down from nearly half its new lending in the June quarter.
The Reserve Bank had ruled that, from the beginning of October, each bank can lend no more than 10% of its total mortgage lending to people with deposits of less than 20%.
In November, BNZ's chief executive, Andrew Thorburn, said his bank had all but stopped providing mortgages to people with small deposits because of the Reserve Bank restrictions.
Westpac's lending to people with less than a 20% deposit shrank in the September quarter.
