One driver said it had taken two and a half hours to travel 66km between Waikanae and Karori on Wednesday morning.
Kāpiti Coast Chamber of Commerce chair Jacinda Thorn said the region had seen a long run of traffic disruptions.
"We have had 10 years of delays with the roads," she said.

"Constant disruption really concerns business because you cannot rely to get to and from Wellington, or for Wellingtonians to come here, you cannot rely that it's going to be a smooth trip."
Although Covid had given people more flexibility to work from home, she said people still needed a smooth trip in and out of the capital.
"People still need to get in and out of Wellington and to have our major route just choc-a-bloc day after day after day is just really hard going."
She understood it was difficult to perfectly time work on a state highway but hoped people making the decisions would take into account traffic flow, especially in the busy holiday period.

"I do think the timing could be better on these things, especially as we are heading into that last two weeks before Christmas," Thorn said.
"You often wonder why not do it overnight on a weekend and make sure everything is working perfectly for when you hit Monday to minimise disruption."
