_{** Measures previously reported under 'discharge' and 'withdrawal' have been restated as 'consumption'. Figures include evaporation from cooling towers, soakage to land, steamfield traps and other minor miscellaneous consumption.}

_{Water volumes for our operations are recorded onsite via meters that measure flow. The flow inlet and outlet determines categorisation of water use, for instance, geothermal fluid outlets to rivers are categorised as 'Discharge to rivers'. Geothermal reservoir consumption is comprised of evaporation / land soakage. Tauhara water use for plant commissioning has been excluded.}
