Police investigating the death of Auckland woman Carmen Thomas today lowered a camera down a hole in a central Auckland construction site, according to a worker on the site.

It was reported yesterday police were looking at digging up concrete laid by construction firm Mansons at Victoria St, in the central city.

Officers spent part of this morning visiting premises in Victoria St asking owners if they had seen anything suspicious and if they had any CCTV footage from around July 1.

A worker at the construction site, who did not wish to be identified, told NZPA police had last week drilled a hole in a concreted area at the site, and returned today with a camera, which they lowered down the hole.

Police spokeswoman Noreen Hegarty would not confirm whether police had been to the site, or why it was of interest.

"All I can say is that we are making progress and that the investigation is ongoing and we still don't know where Carmen is, but every day we're acting on information that has come to light and doing our best to find out what happened to her," she said.

Police were speaking to several people who were helping with their inquiries, some of whom were "of more interest than others", she said.

At the weekend, police confirmed they had found Ms Thomas's recycling wheelie bin on September 1, which had been missing from her Remuera home.

The bin was forensically tested, as was her car, which was found with blood inside on a Hamilton street in July.

There have been no confirmed sightings of her since June 27, her bank accounts had not been touched, and she had not contacted family or friends.

Inquiry head Detective Inspector Mark Benefield said last month it was believed she was murdered.
