He is upportive of the Reserve Bank having a wide range of tools to help manage bank lending, but says nothing more needs to be done at this stage - backing a view across the sector that debt to income ratio limits should not be applied any time soon. "I think the evidence shows there is no need for more tools to be applied. There is no evidence there is a burning platform that needs to be addressed."
Loan-to-value ratios which limit lending to those with a low deposit are said to be part of the reason the market has slowed in recent months prompting calls by the real estate industry to exempt first home buyers who purchase cheaper houses.
McLean believes the rules will need to lifted at some point but not right now. "There is no point in slavishly implementing rules forever.
"From the Reserve Bank's points of view and our own view as a lender when you have had a strong period of inflation - it does increase the risk of a down-turn. There hasn't been a long enough period of stability to justify taking them off."
But he admits it is hard for first home buyers. "It makes it harder to get into houses. It increases the disparity between those in and those not." But he says the worse thing would be to have a massive correction - a drop of 30 to 40 per cent. "That would be a disaster for the New Zealand economy."
