Residents trying to clear black lumps off the popular beach say they are upset at the seeming lack of an official response.
Tauranga resident Dave Lynn said he was walking his dog north up the beach when he found the oil near Tay Street.
The beach north from there was coated, he said.
He had also found three dead birds on the beach.
"You can see the oil everywhere, the moment you touch it, it's sticky and yuck - it looks like big black rocks," he said.
Lynn had been picking up clumps with plastic bags, then throwing it in the rubbish.
He was frustrated that no official response was evident.
"I'm not happy. Something should have happened already," he said.
His wife said the alarm had been raised with the harbour master and on the region's environment line but no action appeared to have been taken.
"There are still people walking dogs in amongst the oil and there needs to be some immediate action."
