NIWA’s 28 m research vessel Kaharoa may merit a place in the Guinness Book of Records, having recently returned from a voyage to deploy a further 42 Argo floats. The floats bring the total deployed by Kaharoa to 439 over four years.

Declining numbers of shellfish is recognised as a problem in many estuaries and coastal areas around New Zealand, and local communities who traditionally gather kai moana are becoming concerned for the future of their customary food source.
In Whangarei Harbour, the Kaitiaki Roopu (caretaker group) has been working with NIWA over the last few years in an innovative project to restore shellfish beds.
