In 2024, we made significant strides with the introduction of Porohita, our new sustainability strategy.
This strategy aligns closely with WM’s core business goals, focusing on five strategic pillars that guide our future sustainability efforts.
From Kaitaia to Bluff, we have over 90 sites that provide comprehensive waste management services, including collections, recycling, composting, and hazardous waste processing.

We are a Toitū carbon reduce certified organisation, meeting ISO 14064 standard and the Greenhouse Gas Protocol.
