Boaties are reminded of a temporary moving exclusion zone around a barge transporting sections of the dismantled Rena accommodation block to the Port of Tauranga.
Work has started on removing the massive "house" - several storeys of crew accommodation from the wreck, which is now on the sea floor at Astrolabe Reef.
Bay of Plenty Regional Council's harbour master Jennifer Roberts said Resolve Fire and Salvage is working on removing large pieces of wreck from Astrolabe Reef and transferring them from the crane barge RMG500 onto a deck barge, the RMG1000 which will be anchored near Motiti Island.
"The RMG1000 will be secured in place by four or more anchors, each marked with a large orange/yellow buoy and lit at night with a yellow flashing light," she said.
"To ensure the safety of the divers and other workers involved in this operation, no unauthorised vessel may enter the temporary Moving Exclusion Zone, the first of which extends out 500 metres from the barge RMG500 during the transit from Astrolabe Reef towards Motiti Island while transporting pieces of the Rena accommodation block."
Anyone breaching the direction is liable to a fine or prosecution, Ms Roberts said.
The direction applies to all vessels, except those authorised by the harbour master or the duty salvage master.
Other temporary moving exclusion zones are expected in the near future are activity on Rena continues.
