We are NIWA, Taihoro Nukurangi
Kia ora, tātou katoa, Ko tēnei te wiki o Te Reo Māori. Ko Te Waka o Taihoro Nukurangi, Ko NIWA me kī. Anei tenei purongo!
Glacier melt: A Time Capsule
Since 2016 enough ice has melted from the South Island’s Brewster Glacier to meet the drinking water needs of all New Zealanders for three years.
Our Climate is Changing
Our climate is changing - we need to act now.
Glaciers Don't Lie
If you think New Zealand's Southern Alps are shielded from climate change – take a look at this. "You can't make a glacier lie.”
Tuna: NIWA working with Ngāti Maniapoto

Measuring chlorophyll, organic nitrogen and carbon levels, PhD student Alex Hayward looks at how much marine life is in the water around the Bay of Plenty during winter.
Marine Acoustician Dr Yoann Ladroit is leading research into using acoustics to find underwater gas bubble flares and then compare these to the chemical composition of water samples taken at the same locations.
NIWA marine geologist Arne Pallentin is looking for telltale gas bubble 'flares"—using a multibeam echosounder—that indicate new volcanic activity in the Calypso Vent Field.
"For us, Whakaari is our whaea, she is our tupuna, and also a place of our mahinga kai. I didn't realise how much I'd missed her..."
Marine geologist - Dr Joshu Mountjoy - is mapping the seafloor landscape around Whakaari/White Island to understand how much sediment was dislodged in the eruption and where it has gone.
Marine Geophysicist Sally Watson, maps the seafloor and takes samples from the water column so we can understand geological processes shaping the volcanic underwater realm around Whakaari/White Island.
It's a special day on RV Tangaroa today - celebrating the Whakatāne High School ball with student Cameron Phillips, one of two Te Rūnanga o Ngāti Awa taiohi on board.
For one last time, Evan Solly starts the engines of NIWA’s research vessel Tangaroa and guides her out of Wellington.

SHMAK Habitat – Visual Habitat Assessment
The SHMAK visual habitat assessment gives your stream a score that you can use to assess changes over time or compare streams.
SHMAK Stream Life – How to Sort and Identify your Benthic Macroinvertebrate Sample
Use an ice-cream tray to isolate and separate your invertebrates. The Benthic Macroinvertebrate Field Guide helps you with identification.
Setting up your Site
The various assessments in SHMAK are done over different lengths (reaches) of stream. Mark out the longest reach first, then shorter reaches.
What is Included in SHMAK
SHMAK is available as a starter kit, a standard kit and SHMAK+. Here we explain what is included in the kit and what extras you need to purchase on your own.
How to Collect a Water Sample
Some SHMAK tests require you to collect a water sample. If you are sending your water sample to a lab for analysis, here's a list of some water quality labs.
SHMAK Water Quality – Visual Clarity
There are two methods to determine visual clarity in SHMAK; the clarity tube (or SHMAK tube) and the black disc method.
