Police have named the five people killed after a boat capsized in Kaikōura on Saturday.
It's believed the 8.5-metre vessel overturned at around 10am on Saturday while members of the Nature Photography Society of New Zealand were onboard.
Those who died are:
- Susan Jane Cade, 63, from Lower Hutt
- Catherine Margaret Haddock, 65, from Lower Hutt
- Diana Ruby Stewart, 68, from Christchurch
- Peter Charles Hockley, 76, from Christchurch
- Maureen Patricia Pierre, 75, from Christchurch
Eleven people were on board the boat when it flipped. Initial reports suggested the boat hit a whale but police have been unable to confirm that.
The Transport Accident Investigation Commission (TAIC) has asked for any witnesses to the incident to come forward.
"The Chief Investigator, Naveen Kozhuppakalam, wants to hear from anyone who saw or recorded what happened - before, during or after the incident," a spokesperson said on Sunday.
"The Commission investigation will run alongside investigations from other agencies. Two investigators are assigned to secure evidence, talk to witnesses, examine any electronic evidence available and look at the circumstances of the incident."
The best way to share information is to email TAIC at info@taic.org.nz.
A police spokesperson extended their condolences to the family and friends of the deceased.
