How long does a building consent take in NZ?
Short answer
By law, your council has 20 working days to process a complete building consent application. But the clock 'stops' if the council asks for more information (an RFI), so in practice it often takes longer — allow several weeks to a few months once you include preparation and any back-and-forth.
Key facts
- Statutory limit: 20 working days for a complete application
- The clock stops when the council requests more information (RFI)
- Incomplete applications are the main cause of delay
- Realistically budget several weeks to a few months end-to-end
The 20-working-day rule
The Building Act gives councils 20 working days to process a building consent from the point they receive a complete application. That's working days, not calendar days, so public holidays and weekends don't count.
Why it usually takes longer
If the council needs more information, they issue a Request for Information (RFI) and the clock stops — sometimes called 'stopping the clock'. The suspension doesn't count toward the 20 days, so a few rounds of RFIs can stretch the timeline considerably.
How to avoid delays
The single biggest lever is a complete, well-documented application. Using an experienced designer and Licensed Building Practitioners, and answering RFIs quickly, keeps things moving.
