How to read these New Zealand figures. The cost is the US national midrange benchmark adjusted by a Auckland, NZ cost multiplier (1.08×) and shown in NZD. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by New Zealand market conditions.
