AI summary

Planning a new build? Understanding NZ construction loans is your first step. You'll typically need a deposit of at least 10% of the total land and build cost.

Funds are released in stages as progress payments to your builder, often with interest-only repayments during construction.

Key contract types include Turn key (price certainty) and Build-only (more flexibility). Be wary of provisional costs (PCs) to avoid budget blowouts. Talk to lenders or a mortgage broker early.
