November 2023
In our November update, more than 42,000 new rates were applied across Auckland, Hamilton, Palmerston North, Wellington, Christchurch and Dunedin. The average rate of increase has certainly slowed since our last update, reflecting an easing in the global supply chain issues that arose throughout the Covid-19 pandemic.
Here are some notable changes since our last major construction cost update:
Cost planning rates
On average, each Element has increased by 0.4% since August. The notable movers were:
- Frame: down 4% due to a reduction in reinforcing and structural steel rates
- Substructure: down 2.9% due to a reduction in reinforcing steel rates
- Structural Walls: down 2.5% also due to a reduction in reinforcing steel rates
- Drainage: up 5% due to increases in plant hire and many drainage items
- Roof: up 2.8% with both metal sheet and metal tiles up
Detailed rates
Each Trade has increased by an average of 0.9% since our August update. The notable movers were:
- Reinforcing Steel: down 16.9% due to a more favourable exchange rate
- Structural Steelwork: down 2.9%, also due to a more favourable exchange rate
- Infrastructure: up 7% due to increases in plant hire and drainage rates
- Demolition: up 5.1% with plant hire and tip fees increasing (except in Hamilton)
- Drainage: up 4.7% due to increases in plant hire and many drainage items
Building costs per square metre
The average change over the six centres (Auckland, Wellington, Christchurch, Dunedin, Hamilton and Palmerston North) since our last major update in June 2023 was 0.3% for non-residential buildings (excluding educational buildings) and 1.1% for residential buildings.
August 2023
In our August mini update, approximately 12,000 current material & labour prices have been adjusted, which has produced almost 8,000 new rates across Auckland, Hamilton, Palmerston North, Wellington, Christchurch and Dunedin.
