The extension would suddenly increase the number of vehicles on Nukumaru Station Rd from 30 a day to 500. She fears Nukumaru Station Rd will become as unsafe as Rapanui Rd.
Her alternative route has better visibility at its intersection with SH3, and there are no houses along it. Instead of running between her farm and David Hopkins' farm it would run between his farm and the railway line.
It's slightly longer, and she's been told it has been disregarded because it will cost more.
She has been offered the current road area in return for giving up her land, but said that land was unlikely to meet organic standards for her high performing dairy farm.
It produces organic milk for Fonterra - the type that fetches the highest export prices of any.
She has resented the implication from council staff that the road is a fait accompli, and said consultation at the Nukumaru end has been lacking.
She was not the only one who has objected, but said the others have all been "talked around".
