We issue price determinations that approve the maximum prices water businesses may charge. The prices we approve reflect an assessment of the efficient costs water businesses need to recover to provide valued services to customers.
We release tariff schedules that set out the maximum prices a business may charge in any year.
We have released Guideline 3 (2025): Varying a Price Determination (Re-opening) which provides guidance on the circumstances in which a price determination may be varied, and the process for varying a determination, including how a water business may apply to the commission to vary its price determination (via a re-opening of the determination).
