Drivers are being urged to be patient as they head away for Wellington Anniversary weekend.
"We're expecting a lot of traffic leaving the capital, then returning on Monday. It's important that motorists are patient and ready for the possibility of hold-ups when they set out on their journeys," NZTA Regional Performance Manager Mark Owen said.
A central police communications spokesman said there were a couple of slow points around Petone and Otaki as traffic headed out of Wellington this evening.
However traffic was no heavier than a normal Friday rush hour, he said.
''It's pretty much business as usual.''
The Transport Agency will close the SH1 northbound passing lanes north of Te Horo, as well as the southbound north of Otaki during peak travel times.
Passing lanes were closed to improve safety and traffic flows when the roads were under heavy demand, Mr Owen said.
"When everyone's crawling, passing lanes can actually disrupt traffic flow by acting as a queue jumping device.
It's not the vehicle in front of you that's holding you up; it's the sheer volume of traffic on the roads.''
