The industry is looking to expand by farming in more exposed locations, but NIWA aquaculture scientist Dr Javed Khan says such growth is likely to be constrained unless new approaches are taken in the hatcheries that supply the juvenile fish to the farms.
This year’s result also means seven of the 10 warmest winters on record in New Zealand have occurred since the year 2000.This was the highest temperature recorded there during winter since records began in 1885 and the equal-4th warmest winter temperature on record for New Zealand as a whole.

Pelorus Ridge was officially granted its title by the New Zealand Geographic Board (NZGB) last week, along with 42 other place names for undersea features in New Zealand waters.Mr Mackay says the naming of Pelorus Ridge carries on a tradition of undersea features connected to NIWA.
“We see it effectively moving around the globe as a seismic lockdown wave,” says Royal Holloway University of London seismologist Paula Koelemeijer, one of the paper’s coauthors.“Earthquakes are often really lower frequencies than the seismic signals from human activities,” says Koelemeijer.
In 2015, New Zealand’s government launched a nationwide effort called Predator Free 2050 with a $17 million (28 million New Zealand dollars) investment to rid the country’s 164,375 square miles of invasive mammals in the next three decades.
As weather systems tracked toward New Zealand from the west and north, they lacked moisture because of cooler eastern Indian Ocean seas caused by the IOD.NIWA’s climate change expectations suggest spring average rainfall decreases for northern New Zealand, including Auckland.
Planning for this voyage has presented a few challenges for NIWA vessel operations manager Greg Foothead as he waited to hear if lockdown restrictions would be eased in time for the ship to leave.
High waves pounding Wellington’s south coast today are being caused by a deep area of low pressure passing the Chatham Islands, according to NIWA forecaster Ben Noll.Mr Noll said the low was responsible for generating strong winds and large waves between the Chathams and mainland New Zealand.
These are broadly defined as hazard monitoring, resilience, diagnostics for essential services like biosecurity, maintaining animal facilities, and infrastructure that requires constant attention (e.g., security of samples, collections and computing facilities), as follows.
A giant squid and several glow-in-the-dark sharks were surprise finds for NIWA scientists last month on the Chatham Rise during a voyage to survey hoki, New Zealand’s most valuable commercial fish species.
On Monday, at 2:11 pm local time, New Zealand’s White Island volcano unexpectedly erupted, blasting a superheated plume of ash, sulfur gas, and steam 12,000 feet in the air and blanketing the crater’s floor in powdered rock and debris.
New information about landslides that occur on the seafloor off New Zealand’s east coast will help scientists better understand why and where they happen, and the types of threats they pose.
A group of microscopic algae that form vast aquamarine blooms off the east coast is the subject of NIWA’s latest Biodiversity Memoir.Measuring as small as three microns (0.003 mm), powerful scanning electron microscopes are needed to look at the algae in detail.
The International Olympic Committee has more granular rules: Transgender women can compete in the women’s category as long as their blood testosterone levels have been maintained below 10 nano moles per liter for a minimum of 12 months.
NIWA Marine Mammal Biologist Dr Krista Hupman says photos of Owha’s injuries taken by members of , a non-for profit organisation set up to conduct research and raise awareness of leopard seals in New Zealand waters, showed blood coming from Owha’s nostrils and smeared on her face.
Microplastics are being fed to snapper, New Zealand’s most popular recreational fish species, at NIWA’s aquaculture research facility near Whangarei in a bid to establish some baseline data about how fish are being affected.
NIWA coastal physicist Dr Joanne O’Callaghan is part of a working group aiming to establish a collaborative New Zealand ocean observing network.Climate change is making its presence felt in New Zealand waters with marine heatwaves, increasing ocean acidification and sea level rise.”.
On the eve of the 30th anniversary since the Montreal Protocol came into force, new research by NIWA scientists reinforces its reputation as the world’s most successful environmental treaty.
Called a Sudden Stratospheric Warming (SSW), it occurs when the temperature of the stratosphere (30-50km above ground) over the South Pole rises by more than 25ᵒC.The Southern Hemisphere is characterised by a cold Antarctic continent surrounded by relatively warm seas.
EQC, GNS Science and NIWA have joined forces to further develop world-leading natural hazards risk modelling for New Zealand. Mr Morgan said the new partnership will broaden use of RiskScape to include more government, council and infrastructure company users, enabling more people to get a better understanding of the potential costs of natural hazards.
With just a few days of autumn left, prolonged warm weather and less rain than normal means some spots across New Zealand are heading for the record books. • Taupo – on track for 2nd warmest Autumn – records began 1949.
It’s a huge step forward for the leopard seal according to NIWA cetacean biologist Dr Krista Hupman, who largely attributes this success to Owha who made the Waitemata Harbour her home in 2012. NIWA Cetacean Biologist/Ecologist Dr Krista Hupman has helped getting leopard seals a new residential status in New Zealand waters.
