Commerce Commission to regulate new levy system replacing development contributions
Councils will be able to charge developers a new development levy from 2029, with the Crown also required to pay it, under housing infrastructure reforms confirmed this week by Housing minister Chris Bishop (pictured).
The change replaces development contributions, the current charging system long criticised as inconsistent and prone to leaving existing ratepayers covering some of the cost of new subdivisions. The Commerce Commission's confirmation that it will act as the new system's independent regulator was one of three significant changes made following consultation with councils and developers
Levy areas narrow, and the Crown starts paying its share
Under the revised approach, councils must now set up separate levy areas wherever forecast infrastructure costs differ substantially, a tighter requirement than the broader levy areas originally proposed. Core government departments — including the Ministry of Defence and the Department of Corrections — will also be required to pay development levies for the first time, bringing them into line with Crown entities such as Kāinga Ora that already do.
"The new development levy system will make sure that growth pays for growth," Bishop said.
The reform follows warnings from Auckland Council about the scale of the funding gap it already faces: council staff estimated that servicing roughly 50,000 to 60,000 "unanticipated" homes — approved outside its planned growth areas — could cost the council up to $5 billion once water, wastewater and running costs are included.
Commerce Commission to write the methodology
That funding gap is exactly what the new methodology is meant to prevent: the Commerce Commission's role will include establishing nationally consistent methodologies for calculating levies, setting disclosure requirements, and monitoring compliance. The Commission said the new function builds on its existing experience regulating monopoly infrastructure sectors such as electricity and gas.
Local Government minister Simon Watts said the shift addressed concerns raised directly by industry.
"Developers raised legitimate concerns about over-charging and cross-subsidisation," Watts said.
Budget 2026 has set aside $30 million to build the Commission's new regulatory function between 2026 and 2030. The Local Government (Infrastructure Funding) Amendment Bill is expected to be introduced in early 2027, with councils required to have levies in place by 2030.
With the detail still to be legislated, the practical impact on buyers remains uncertain — but for advisers, the reform already carries direct implications for borrowing capacity and property investment decisions: a levy structure tied more closely to actual servicing costs could push up prices in some greenfield developments, while more predictable charging may ease uncertainty for property investors weighing new-build purchases ahead of the 2029 rollout.
