The closure will mean gridlock in Waipū and drivers who are so fed-up they do not want to stop, said shop owner and longtime resident Patsy Montgomery.
Gwynne also felt for hospitality businesses further north, saying the closure will stop visitors coming to Northland.
He thought if the highway had to close, it would’ve been better if it was after Easter when visitor numbers drop.
Residents are also concerned about the impact of the highway closure on them.
Mangawhai local Chris Hill said the closure is “heartbreaking for businesses” and will also put a lot of pressure on the roading network.

The detour route has three one-lane bridges which become congestion chokepoints.
Mangawhai local Tony Neels said the traffic created by the Brynderwyns closure is so bad many locals choose to stay at home.
“The roads are already under stress because of the last weather event. They [the council] have been frantically trying to fix the roads but it’s a patch-up job.”
Neels said NZTA needed to think about traffic management at busy intersections in Mangawhai, such as having someone on point duty at the Insley St roundabout, where queues can stretch 1.5km.
“We’ve got lots of roundabouts now but it still doesn’t let traffic flow when it’s under pressure,” he said.
Mangawhai resident Ailsa Trevithick accepted there was no good time to close the Brynderwyns route but said there needed to be better signs through the area for drivers unfamiliar with Mangawhai.
She had heard of people getting lost during the last diversion.
Whangārei mayor and Northland Mayoral Forum chairman Vince Cocurullo said it was good the closure was timed to avoid the busiest part of the season.
He also hoped visitors would continue to come north when the highway is closed, allowing time in their travels to stop along the way.
One business operator who is pleased about the closure is Amy Frater of Mangawhai Village food truck Cow Shed Pies.
Frater said she did a roaring trade during the last closure, with drivers happy to make a quick stop to grab a pie and drink.
