Tuna: NIWA working with Ngāti Maniapoto
Maniapoto Māori Trust Board and NIWA worked collaboratively during 2018-19 to support Ngāti Maniapoto whānau to reconnect with and participate in the assessment of their waterways according to thei
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.

A video about The world's most mysterious fish. NIWA researchers are working with iwi to try to unlock the secrets of New Zealand tuna—freshwater eels.
SHMAK Water Quality – Nitrate
The nitrate test included in SHMAK is a colorimetric test. Where to order additional Aquaspex Microtest® Nitrate-N kits.
SHMAK Water Quality – Temperature and Conductivity
Temperature and conductivity are two easy measurements you can take in your stream. Here's how to use a temperature logger.
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.
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.
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.
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.
SHMAK Stream Life – Collecting Benthic Macroinvertebrates in Muddy-Bottom Streams
If your stream has a muddy-bottom or soft-bottom (made of silt or mud), you need to use a different method than if your stream has a stony-bottom.
SHMAK Water Quality – Phosphate
Phosphate is measured in SHMAK using the Hanna Instruments Phosphate Checker. Where to order phosphate checkers and reagents.
SHMAK Stream Life – Periphyton
How you can assess the types and amount of periphyton: communities of algae and cyanobacteria attached to the sediment surface or plants.
