Labour's new leader appears to think he can manage New Zealand's financial system better than the Reserve Bank. If he was in power now, he says, he would not allow the bank to include first-home buyers in its mortgage lending restriction to take effect from next week.
The bank is about to limit the amount of lending that retail banks can do on deposits of less than 20 per cent of the price of the house. It is acting out of concern that banks are becoming too exposed to the risk that another house price bubble will burst, causing prices to fall. If that were to happen, the consequences for banks might be costly but for low-equity first-home owners it could be catastrophic.
The little equity they have amassed could be wiped out, leaving them owing the bank more than their house is worth.
If that sounds bad enough, other policies espoused by David Cunliffe would make their position even worse. If elected, he says, Labour would exempt first-home buyers from the new lending limits until its capital gains tax took hold and its low-cost house building programme took effect.
Nothing would be more likely to bring about a fall in house prices than a capital gains tax and an increase in state housing. If Mr Cunliffe had the interest of first-home owners at heart he would not only limit their access to low equity loans, he would do so well in advance of his other proposals.
