More than a month after oil spilled from the stricken container vessel Rena, closing the coastline between Mt Maunganui and Maketu, officials have lifted access restrictions to all areas except a section of Papamoa Beach and Maketu Spit, where clean-ups are continuing.
But beachgoers are still urged to "exercise caution" and an iwi-imposed rahiri banning the collection of seafood will remain in place until authorities give the all-clear.
Maritime New Zealand's national on-scene commander, Mick Courtnell, said he could order the beaches closed again if he needed to.
"If I need to clean them, I close them to the public ... if they become re-oiled, then I'll close them again."
Tauranga Mayor Stuart Crosby said it was "the news we have all been waiting for".
