Members of the public assisting in the search for the missing Waikato family are urged to stay safe to avoid another search and rescue.
The search for missing man Thomas Phillips and his three children resumed this morning with a ground-based coastline search, police confirm.
Phillips, 34, and his three young children Jayda Jin, 8, Maverick Callum-Phillips, 6, and Ember Phillips, 5, were last seen in Marokopa nearly a week ago.
Waikato West Area Commander Will Loughrin said they were aware members of the public were eager to assist in the search.
"We understand people want to help. However, the search area is extremely challenging and we don't want a situation where people become injured or trapped, causing another search or rescue incident," he said.
