For traffic travelling south and turning left into Portland Rd it would be made easier with the introduction of a slip lane. Wire-rope barriers and a flush centre median to separate opposing traffic would all add to safety improvements at the intersection.
But landowner Dave Gundry, who lives on Portland Rd, says $10,000 offered for a strip for road improvements along his property, bordering Portland Rd and another strip along SH1, was not enough.
Gundry said NZTA wanted to take 2500 square metres off his 10 acre block.
Gundry had owned the property for 35 years and said when he bought it he did not expect to have strips carved off it.
He had seen the aftermath of crashes at the busy intersection and he supported the safety work being done.
"I've got nothing against what they are doing to make it safer, but $10,000 is an insult.
"They shouldn't be able to dictate. I say the land is worth about $50,000 and that's reasonable. And it's the principle of the thing I thought we had rights. Rights to speak, rights to object, rights to negotiate."
He had not had the land recently valued.
NZ Transport Agency senior system manager Kevin Reid said while he could not discuss individual cases processes were followed to reach an amicable agreement with the landowner. He said it was the Crown, and not NZTA, who purchased the land.
Consultation with landowners began in March 2017.
Reid said NZTA got an independent market valuation and would pay for the landowner to have a separate valuation done.
"The valuations are used as the basis for negotiation."
Construction is planned to start in December or January, subject to gaining all necessary approvals.
