Coastguard Mana are currently on standby for tasking by Police to resume the search for the missing swimmer [2] at Titahi Bay, and/or support other operations such as the Police dive squad.
Update: We were eventually stood down at the end of day 3 with no further assistance required. The Police dive squad and Titahi Bay Lifesaving Club continued the search with nothing found.
