As the long weekend wraps up the inevitable traffic queues are forming as holiday-goers return home.
Motorists are reporting crawling traffic and congestion south-bound between Levin and Otaki - a 20km distance that is taking about 40 minutes to navigate.
New Zealand Transport Agency central region spokesman Anthony Frith said there was almost always a bottle-neck near Otaki on the last day of a long weekend.
"It's an incentive for people to ask their bosses for an extra day off really,'' he said.
Traffic management measures had been put in place over the last three days to ease traffic flow.
A side road in the area had been closed off and passing lanes had been shut down to stop drivers jumping the queue, which frustrated other drivers and could cause crashes, Frith said.
"Basically until the expressway is built there will continue to be queues at this time.''
Traffic congestion was easing south of Otaki and SH2 from Wairarapa to Wellington was flowing smoothly.
