Maritime New Zealand's Rena disaster Incident Command Centre is now located at industrial premises in Glenlyon Avenue in Greerton.

It's the third move for the ICC since the container ship Rena struck Astrolabe Reef on October 5.

Maritime New Zealand's new Rena disaster Incident Command Centre.

The first temporary base was in a shed behind the Classic Flyers museum near Tauranga Airport.

The magnitude of the disaster and the range of responses required saw the Foodtown site on Cameron Road acquired the following week.

During the height of MNZ's management of the disaster response, the former supermarket housed 300-400 people.

They were working in small teams on different aspects of the response.

Foodtown was also the scene of daily press conferences attended by a full gamut of national and international media.

The first press conference held on Thursday outside the new Greerton site was attended by local radio, SunLive and a Wellington based reporter.

It is easy to find, being the only Glenlyon address with new Alcatraz fencing – and a security guard outside.

A brief glimpse under the sliding door revealed that he is protecting a warehouse containing a few tables and some maps on the walls.

At the Thursday press conference, MNZ national on scene commander Rob Service said the relocation recognised the reduction in management requirements.

However, he was quick to assure that it doesn't mean the Rena disaster response is being abandoned by Wellington.

'We are here for as long as it takes,” says Rob.

Contingency plans are in place to expand the ICC operations should developments require it.

There is still oil leaking from the broken ship, but Rob is pleased the rate of leakage appears to be reducing.

Clean up teams are still working on Matakana Island, Mount Maunganui and Leisure Island.

The number of oiled birds being found is also reducing; one was found on Wednesday.

There are 17 penguins at Massey University in Palmerston North and four are being cared for in Tauranga.

Maritime New Zealand is expecting to be able to release eight of the birds next week.
