An environmental crisis is unfolding in the Manawatū, where thousands of native fish and other wildlife have been found dead or dying on a dried-out lakebed at Pukepuke Lagoon.

The lagoon, located between Himatangi and Tangimoana, has completely dried up, leaving behind widespread devastation across what was once a thriving wetland ecosystem.

Authorities including Horizons Regional Council, the Department of Conservation, and local iwi and hapū were alerted after the exposed lakebed was discovered littered with dead and struggling aquatic life.

The scale of the die-off is being described as unprecedented, with thousands of tuna and other species affected. The lagoon has historically experienced low water levels during dry periods, but the complete loss of water and resulting mass deaths have shocked those familiar with the area.

An investigation is now underway, with early indications pointing to a combination of long-term pressures. These include groundwater extraction, drainage systems linked to surrounding land use, and increasingly extreme weather patterns.

The lagoon holds deep cultural and environmental significance, particularly for local iwi, with species such as tuna considered taonga and integral to whakapapa and identity. The loss is being felt not just ecologically, but culturally across the region.

Access to the site has been restricted, with efforts focused on salvaging any surviving wildlife and understanding how such a collapse occurred. Nearby lakes in the region have also recorded critically low levels, raising concerns about wider environmental stress.

The event is also highlighting broader issues facing wetlands across Aotearoa, with significant losses over the past century due to land development and water management practices.

As investigations continue, there are growing calls for stronger protections and long-term solutions to prevent further environmental damage and safeguard remaining ecosystems.
