Local authorities say the Tauranga oil spill is under control although several birds were oiled and soiled in the incident.
Two shags were put down after the spill this week but a local conservationist said initial searches found no oiled penguins in the area.
A Mobil-owned pipe leaked on Monday and the Bay of Plenty Times reported bad weather had hampered efforts to clean up the unknown amount of oil.

'Disgusting' oil spill reaches estuary, claims wildlife
Mauao Area Wildlife Trust director Julia Graham said the trust would check again later today and tomorrow.
"The penguins can go all through the harbour ... at this point no oil was noticed on Mauao and Leisure Island and around their burrows," Ms Graham said.
She said the Trust was formed after the Rena disaster but the latest spill was tiny in comparison.
The Bay of Plenty Regional Council said its oil response staff met with Iwi representatives today at the oil clean-up site on the Maungatapu foreshore to plan the next stage of the work.
"Oil at the Bridge Marina was well contained by booms and being sucked out by sucker truck," the council said in a statement.
Wildlife appeared to have not been badly affected although two shags were put down, the council said.
"Several other lightly oiled birds were spotted but not caught. They will be left to clean themselves as the small amount of oil is not likely to harm them," the council added.
Regional on-scene commander Adrian Heays said the council was grateful to homeowners who allowed the clean-up crews to use their properties to access the foreshore and set up a decontamination station.
The council said boaties should not clean their boats or gear with "any aggressive chemicals" as this could cause more contamination. The council advised boaties to ask marina operators for advice.
The council said oil slicks or oiled vessels should be reported to the regional council's pollution hotline on 0800 884 883. People could also email info@boprc.govt.nz.
Oiled wildlife could be reported to the Department of Conservation by calling 0800 362 468.
