19 Nationwide Values Average Value of Housing Stock - New Zealand Annual and Quarterly Change in Value Nationwide values ticked up a fraction in the latest month according to the latest QV house price index. The general trend is still flat however. The previous rates of value increase that we saw a year ago have eased right across the country. It is unlikely that values will rebound again in the same way that we have seen in response to previous rounds of lending restrictions imposed by the Reserve Bank. Nationwide weakness is more likely to continue until after the election in September when it will become clear what policies on migration, housing supply, housing investment, and affordability have won through.
