Work to move a section of the Kurow-Duntroon Irrigation Company pipeline underground will begin in April.
The company was issued an abatement notice by the Waitaki District Council in August last year, after criticism the pipe spoiled the State Highway 83 scenery and blocking the view breached the company's consent.
However, it was later cancelled and a new notice was issued directing the company to reach project milestones by September this year.
Chairman Jock Webster said the company asked for more time to complete the work to satisfy all parties.
"We asked the district council to extend the abatement notice for another year so we didn't have to shut it off during the irrigation season, which would have been very debilitating on the farmers in the district," Webster said.
