Research

Ngā Waihotanga Iho, the estuarine monitoring toolkit for Iwi, has been developed to provide tangata whenua with tools to measure environmental changes in their estuaries. While Ngā Waihotanga Iho is based on sound science principles, it is also underpinned by tangata whenua values.

Using a collaborative case study approach, the aim of this project is to assist tangata whenua to bring together different, yet complementary knowledge systems - distinct Māori knowledge and conventional fisheries and ecosystem information.

Farmers rely on irrigation, but water is a limited resource and little is know about how to manage it best. NIWA has developed a hydrology and soil science model to show how much to water, and when, to get the best results.

New Zealand's rivers and streams, and the diverse fish that live in them, are worth protecting. But the question of which species prefer to live where was unanswered until NIWA completed this major survey.

The kōaro was once abundant in the Te Arawa lakes near Rotorua in New Zealand’s North Island. NIWA has assessed the viability of restoring this species in the region.

This research aims to provide better predictions of changes in the ocean and climate system, particularly the way in which the ocean around New Zealand regulates greenhouse gases and clouds.

By analysing air trapped in ancient ice we can see how wetlands and permafrosts responded to warming periods in the past, and help predict what will happen in the future.

NIWA and the Te Arawa Lakes Trust have developed a sustainable management framework for customary fisheries in Te Arawa lakes, as part of a joint 3 year research programme.
