S&P Global Ratings revised its risk trend on New Zealand to positive from stable after housing-related imbalances in the economy moderated.
"We are revising our economic risk trend to positive given our view that the risks facing New Zealand's financial system have stabilised. This reflects a slowdown in the rapid rate of growth in residential house prices and private sector credit extension as the credit cycle matures," the ratings company said.
However, "we do not expect an improvement in economic risk will impact our issuer or issue credits ratings on New Zealand bank and non-bank financial institutions," it said.
The key drivers in the slowdown of house prices and private sector credit growth are tighter bank lending standards and the macro-prudential tools implemented by the Reserve Bank of New Zealand.
It says Government policy initiatives may contribute to a continued slowdown.
