Currency and measurements
Prices use NZD and the existing New Zealand pricing model. Changing measurement units does not change the pricing country or convert UK rates.
Square metres (m²). Room replacements use room counts where requested.
What to check
Confirm council consent, development contributions, utility connections and site/ground hazards. Auckland references and broad regional factors need local quotes.
Review the result’s tax basis, assumptions, inclusions and exclusions. These are indicative budgets, not contractor quotes or confirmation of regulatory compliance. Unsupported work needs a separate price.
