It's too early to speculate what caused a fire and subsequent sinking of a vessel off the coast of Whakatane yesterday, a Transport Accident Investigation Commission spokesman has said.
Rob Thompson, chief executive of the commission, spoke to media in Whakatane this afternoon and said it was not yet known how the fire started on PeeJay V.
The White Island Tours boat carrying 53 passengers and seven crew caught fire yesterday afternoon, forcing those on board to jump into the water or get into safety boats.
No one was seriously hurt.
Mr Thompson said it would take several weeks to gather information from passengers and crews.
