The seas and oceans around New Zealand are warming much faster than the global average, according to a report published today, commissioned by the country’s government.

According to the report titled “Our Marine Environment”, New Zealand’s waters are warming 34% faster than the global average.

Surface temperatures in four regions have risen by an average of 0.16°C to 0.26°C per decade between 1982 and 2023.

Researchers also found a link between climate change and disruptions to major ocean currents between New Zealand and Antarctica.

The study also revealed that many species—such as the yellow-eyed penguins (hoiho) that live in New Zealand—are struggling to adapt to the warmer and more acidic waters.

“Based on these findings, we need to change the way we manage New Zealand’s marine environment,” warned Shane Gedge, marine advisor at the Ministry for the Environment.

“We now have enough evidence to take action, and any further delay risks causing more damage to our marine ecosystems,” he added.

Researchers also found that sea level rise is accelerating in many areas. It’s estimated that over 200,000 homes in New Zealand are located in flood-prone zones, a risk partly attributed to this phenomenon.
