Because of the splashback, it was believed to be a large amount.
Orevich said the toxic spill was concerning for the local environment as it coats everything.
Luckily the spill has been somewhat contained thanks to Whangārei District Council with a pump truck and NRC putting material down to soak it up. However, some staining on the stream bank and discolouration in the water remains.
She said residents were reported to be “really angry”.
Luckily the spill was in a sheltered area, and not near birds’ food sources, she said.
On social media, NRC asked the public for help.
“We’ve worked with our colleagues at Whangārei District Council to remove as much of the oil as possible before the tributary, at the end of Gillingham Rd, is flushed in the next rainfall event.”
“Unfortunately, complete cleanup is impossible without causing further damage to the awa [river] which means the streambanks are stained and some discolouration is still present in the wai [water].
The NRC said it wanted to find the offender and “we’d like to hear from anyone who can help”.
Orevich said the incident was a reminder to dump oil responsibly.
“They can take it elsewhere to do it,” she said.
In Whangārei, waste oil, household batteries and paint can be taken to the Re:Sort Centre at Kioreroa Road on non-amnesty days.
