Question

What are Watercare Infrastructure Growth Charges and why did they rise 20%?

By Mark Pervan, Director, City Builders Association Limited · Published 2026-10-26

Answer

Infrastructure Growth Charges are one-off fees paid when new developments connect to Auckland's water and wastewater network. They fund bulk infrastructure such as transmission pipes, pump stations, reservoirs and treatment capacity. Watercare raised them 20% from 1 July 2026, which it says is the minimum increase required under its current regulatory settings.
