The search for a missing diver at an Auckland lake will resume at first light today.
The police national dive squad arrived from Wellington about 7pm yesterday and made a decision to continue the search this morning.
Emergency services were called to Lake Pupuke on Auckland's North Shore about 1.45pm after an eight-person trainee dive team, made up of three instructors and five trainees from Tauranga-based outdoor education provider Adventure Education, reported problems.
A student diver was recovered from the lake and another student diver remained missing, Inspector Matt Rogers of northern police communications said.
A third diver was injured in the water and was taken to hospital for further medical treatment, he said. The diver has since been discharged.
It is not yet known what caused the tragedy.
Adventure Education general manager Sharon Sutherland said the team's total focus was on finding the missing diver and they were helping police with their investigations.
"We will be doing a thorough investigation into what has happened here today, but our immediate priority is to find the missing person."
A Westpac rescue helicopter circled the lake yesterday afternoon, while a boat searched for the missing person.
A large emergency team also searched the edges of Lake Pupuke.
The Department of Labour said an inspector had been sent to the lake to make initial inquiries.
