Police are looking for a man seen acting suspiciously near the scene of a fire that destroyed a family home in Long Bay Regional Park.

The Auckland Council-owned home of Mellissa, Scott and Matthew Marchant was gutted in the Monday afternoon fire.

A fire service spokeswoman said the fire was considered suspicious.

Waitemata Police yesterday posted a photograph of a man on their Facebook page and asked for the public's help in identifying him.


"The man in these pictures was seen acting suspiciously near the property and was seen trying to open the doors of several cars and buses in the area," the post said.

"Though the picture quality is poor, he was wearing a black cap, black long-sleeve top and black trousers with a white strip. Police are hopeful that someone will know and recognise the man."

Anyone with information should call North Shore CIB on (09) 477 5261. Information can also be given anonymously by calling Crimestoppers on 0800 555 111.

A Givealittle page has been set up for the Marchant family, who lost everything in the fire.

Donations totalling $14,450 had been made by this morning.
