She said that the road will be sealed where it passes occupied houses, not its entire length, provided the council agrees to fund the local share when it meets next Thursday, "and I am sure it will".
Pipiwai Titoki Road Action Group spokeswoman Alex Wright said it was great news after the residents had spent more than 12 years fighting the issue.
'"We've put a lot of time and effort into getting this far, but this is only the start really and we'll keep lobbying to get the whole of every road sealed," Ms Wright said.
She said it was a relief to finally be taken seriously by NZTA over the major public health issue the dust caused the residents.
Another Wright Rd resident, Daryl Barge said the announcement was great news, but was not the end of the matter as far as he and other residents were concerned.
"They've already sealed parts of the road in front of many houses, but that wasn't enough as the drag from the dust is about 500 metres when it comes off the metal," Mr Barge said.
"So that's proved pretty ineffective, so I'm picking they are going to add to those existing strips to make them longer, which will help. But over time we'd like the whole road sealed.
"That's our ultimate goal, and this is definitely a step in the right direction, but it's been a long time coming. This is a public safety issue."
Ms Mai said WDC's application had to reach a very high bar. Wright Rd is unique because it has a very high volume of logging traffic which will continue long into the future.
"We celebrate this outcome. We are the first council to apply for funding using the agency's new dust hazard criteria, we have been successful, and we intend to apply for more funding for the rest of the road, and potentially other roads in the district," she said.
"Physical work on the road should happen next summer."
NZTA said the council looked at various options and has determined that chip sealing was the best practical option to reduce potential adverse health effects of dust exposure at these locations.
"The Transport Agency understands the concerns caused by dust for residents along Northland's very large rural and unsealed road network", NZTA's Northland Regional Director, Ernst Zöllner said.
"We're delighted to be able to support Whangarei District Council to actively manage dust issues through their maintenance programmes."
