What affects the cost of a wood deck addition
- Decking material
- Pressure-treated pine is cheapest and highest-ROI; cedar and tropical hardwoods cost more upfront and recoup slightly less.
- Size & height
- Square footage sets the baseline; a raised deck needs taller footings, more structure and more railing, all of which add cost.
- Railings & stairs
- Linear feet of railing and the number of stair runs are surprisingly large cost drivers on smaller decks.
- Site & footings
- Sloped or soft ground means deeper footings and more grading; a flat, accessible yard keeps the base cost down.

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.
