Latest From Grim


Grim, a male juvenile white shark SPOT tagged off Stewart island in March this year has averaged 108km a day since being tagged!… The 2.8-metre-long shark, named Grim by conservation scientists, surprised researchers who are tracking him with his reluctance to follow his peers and move north to the tropics. In three months, Grim has travelled more than 2000 kilometres, averaging 108km a day on a journey that has taken him from Stewart Island to the Chatham Islands, then North towards Tonga before about turning to return to the Bay of Plenty.

The Department of Conservation and National Institute of Water and Atmospheric Research had tagged six sharks in the summer, but Grim was the only one that chose to stay around New Zealand. “He’s on a real tiki tour around the North Island.”  Yesterday, Grim was 7.5km off Te Kaha, the closest to shore he had been since setting off on his journey on March 29.

White sharks were protected in New Zealand in 2007 under the Wildlife Act, and the DOC study being carried out in conjunction with NIWA is to learn more about their movements.  Earlier in the study, another shark named Shack surprised the team for diving to a depth of 1200 metres while migrating from Stewart Island to Brisbane.  This is the deepest dive recorded so far for a white shark.
