Complaints about changes to the Kokotau and Millars Rd intersection have left Carterton councillors pledging to be more involved in the planning process.
Speaking at this week's council meeting, Mayor John Booth said the contractor had done a good job on the improvements, which included a new T-intersection, despite design faults that mean consultation was needed before undertaking similar work in future.
Councillor Bill Knowles was disappointed with the new layout, which had "no relevance to a farming community".
Mr Booth said council would be more involved in the upcoming upgrade to Para Rd.
Pinfolds Transport director Steve Pinfold said he had raised concerns with council regarding changes to the road, which meant trucks picking up stock could no longer park near the corner.
