Impacts of mining on water quality and mahinga kai.

NIWA has working relationships with hundreds of organisations in New Zealand and overseas.

These datasets are available in a range of formats.

The sex of tuna is not determined genetically, as in some other organisms.

Methane (CH4) is the second most important greenhouse gas after CO2 that is produced by human activities.

Like the GMS satellite, the NOAA Series of polar orbiting satellites (operated by NOAA, the US National Oceanic and Atmospheric Administration) are a component of the World Weather Watch meteorological satellite network.

Because of its exposure to disturbed weather systems from the Tasman Sea, this climate zone is often quite windy, but has few climate extremes.

NIWA’s climate scientists can now confirm what you may have suspected. After carefully poring through more than a century’s worth of data, it has been officially determined that winter 2022 was Aotearoa New Zealand’s warmest and wettest on record.

The 3-panel Soil Moisture Deficit (SMD) map shows the historical soil moisture deficit at the date shown (left), the soil moisture deficit at the same time last year (middle) and the current soil moisture deficit (right).

The New Zealand Palaeotsunami Database (Database) brings together all known information about tsunamis that occurred prior to written records.

Here are some simple steps to minimise the effects of dairying on water quality and mahinga kai.
