What does science tell us about New Zealand eels?

For more than 20 years NIWA scientists have been nurturing three plants that are the only examples of their kind in existence.

NIWA scientists have set up air quality sensors every 100 metres across Arrowtown in what is believed to be the world’s densest air monitoring network.

This is one of the most extreme drought events for Auckland in modern times and similar to one experienced in 1993/94.

Seven weeks of lockdown has provided evidence of how pollution can vanish overnight with benefits for the environment and individuals, says NIWA air quality scientist Dr Ian Longley.

NIWA’s flagship research vessel Tangaroa will sail out of Wellington Harbour on Sunday for the first scientific voyage since the lockdown.

Please note that this will be the final Hotspot Watch update for this season. Weekly Hotspot Watches will return in the spring.

NIWA scientists are seeking help to sniff out smoke in a bid to help improve air quality in New Zealand.

Analysis of drought conditions across New Zealand this year shows it is one of the most severe on record for some regions.

Minor to moderate soil moisture decreases across the entire North Island with severe meteorological drought in parts of northern Auckland, Coromandel and southern coast of Hawke's Bay. Drier than normal conditions are still present in the top of the South Island but significant rainfall in the west.

Traffic pollution measurements in Auckland since Level 4 restrictions were eased on Tuesday have shown levels soaring even higher than those before lockdown, NIWA air quality scientists say.
