Westpac New Zealand has pulled back on its level of mortgage lending where it wears the bulk of the risk, amid increasingly volatile house prices.
The lender has reduced its level of lending above an 80 per cent loan-to-value ratio (LVR) to about 21 per cent from about 22 per cent a year after house prices in Auckland and Christchurch rose at a level Westpac wasn't "comfortable" with, said chief executive Peter Clare.
That comes as the bank introduced a 25 basis points margin on low equity loans last week, though Clare said it didn't look like a bubble yet.
"Increasing house prices, particular in Auckland and Christchurch, were not something we were comfortable with," Clare said.
The reduction in high LVR lending comes as the Reserve Bank prepares for its six-monthly financial stability report next week, where it is expected to give some guidance on how it will use its new macro-prudential tools. The new tools allow the central bank to rein in asset bubbles, and include the ability to limit the level of high LVR lending.
