The new report, by the Ministry for the Environment (MFE) and Stats NZ, backs up growing research that sea levels are rising fast.

Our Marine Environment 2022 is the third report on the state of the country’s marine environment.

It brings together previous research, including that sea levels are rising twice as fast as previously thought, and new findings to paint a picture of the state of our marine environment.

Latest data now shows ocean acidification is up 8.6%, from data collected between 1998 and 2020.

Marine heatwaves are becoming more frequent and severe, and on average the sea-surface temperature increased by 0.1C to 0.2C per decade across the four oceanic regions.
