In the past 10 years, more weather records have been broken than in any other time in New Zealand’s history.

Our work

NIWA is leading a New Zealand partnership to map the South and West Pacific Ocean's seabed as part of a worldwide initiative to map the entire globe’s seafloor.
Does climate change affect the position of the Subtropical Front around New Zealand? This has important consequences for New Zealand's climate and biological productivity.

2019 New Zealand Climate Summary
NIWA climate scientist Nava Fedaeff presents the NIWA annual climate summary for New Zealand 2019.
Annual Climate Summary for 2018

New Zealand’s equal-2nd warmest year on record. Annual temperatures were above average across the majority of New Zealand, including much of the North Island as well as the western and southern South Island. See complete 2018 Annual Climate Summary details.

Weather Tips - What is El Niño?

El Niño. We hear it being brought up in the news quite a bit, but what does it actually mean? No, it's not a type of yoghurt!

In the 2010 NIWA Report on the seven-station temperature series (Mullan et al., 2010), two alternatives were offered for the adjustment at January 1945 between the records for Hokitika Town and Hokitika Southside. An offset of -0.52°C (a negative value meaning the new site is colder) was calculated by comparing the changes at Hokitika from 1935-1944 to 1945-1954 with those at four comparison sites. An offset of ‑0.68°C was calculated from a direct comparison between the two Hokitika records from the overlap of 30 months for August 1943 to January 1946.

In April and May 2016, the Martinborough EWS (agent 21938)1 experienced some technical difficulties, and a number of 9 am observations were missing
El Niño accounts for less than 25 percent of the year-to year variance in seasonal rainfall and temperature at most locations in New Zealand, however its effects can be significant.

Northern New Zealand
Kaitaia, Whangarei, Auckland, Tauranga

This is a sub-tropical climate zone, with warm humid summers and mild winters. Typical summer daytime maximum air temperatures range from 22°C to 26°C, but seldom exceed 30°C. Winter daytime maximum air temperatures range from 12°C to 17°C. Annual sunshine hours average about 2000 in many areas. Tauranga is much sunnier with at least 2200 hours. SW winds prevail for much of the year. Sea breezes often occur on warm summer days. Winter usually has more rain and is the most unsettled time of year.
