In the twice-year financial stability report, the central bank said "both mortgage credit growth and house price inflation have eased to more sustainable rates, reducing the riskiness of banks' new housing lending."
Against that backdrop, the bank eased its loan-to-valuation restrictions on banks' mortgage lending slightly, allowing banks to now make up to 20 per cent of their new mortgage lending to borrowers putting down less than a fifth as a deposit, up from 15 per cent currently.
As well, the deposits investors must have has been eased to 30 per cent of a property's value, down from 35 per cent previously.
OMF private client manager Stuart Ive said that while the kiwi got a lift from the central bank's comments, it remains tightly range bound just below 68 US cents and is "poised ahead of G20 this weekend where markets await the outcome of a meeting between the US president and China's Xi."
Investors had been cheered by comments from White House economic adviser Larry Kudlow who confirmed the two would meet over dinner and held open the possibility that the two countries would reach a trade deal.
Ahead of that, Ive said investors will be watching for the second reading of the US third-quarter gross domestic product, which is tipped to come in at 3.6 per cent and that will likely cap any gains.
