A JOINT project between Hawke’s Bay Regional Council (HBRC) and NIWA with Ministry of Primary Industries (MPI) co-funding mapped a part of the seabed known as the Wairoa Hard.
The Wairoa Hard covers just over 300 square kilometres of northern Hawke’s Bay between the Moeangiangi and Wairoa Rivers and extends
out 18 kilometres to where the ocean floor is 50 metres deep.
It is named for its coarse cobble substrate and is an area of national importance as it provides a nursery for juvenile fish, snapper, sharks, John Dory and trevally.
“This is an area that has been identified as significant in the coastal marine area for a number of services and functions, but we don’t know how it is doing health wise and we need a much better understanding of that,” said HBRC senior coastal scientist Anna Madarasz-Smith.
NIWA’s multipurpose coastal research vessel the Ikatere arrived in the Hawke’s Bay on April 12. The Ikatere is a 13.9 million custom-designed catamaran which collects high-quality hydrographic data and has been involved in the mapping of more than 1,500,000km² of New Zealand’s seafloor using multibeam echosounder equipment.
