Police divers are being brought in to the search for missing Christchurch builder Michael McGrath.
The 49-year-old was last seen at his Halswell home more than two weeks ago.
Mr McGrath, a builder, lived alone. His brother has said such a disappearance was completely out of character.
The police scoured two houses last week as part of their investigation into his disappearance.
They said they had called in divers to help search water in Halswell today.
They are expecting to complete a scene examination of a property on Candys Road tomorrow.
