The NZ Transport Agency is urging Auckland motorists heading away for Easter to plan ahead to avoid delays on the roads.
The agency has created maps to show the expected peak holiday traffic times to help motorists decide the best time to travel to avoid queues.
The maps show the busiest times based on previous years' travel patterns.
NZTA senior journey manager Neil Walker said: "We know we'll see large numbers of people heading off to their usual holiday destinations and that makes queues and delays inevitable at the most popular times."
Heading out of Auckland, the traffic will start to build on State Highway 1 in both directions from midday on Thursday right through to about 8pm.
On Friday, traffic is likely to remain heavy from 7.30am for much of the day especially between Puhoi and Wellsford, on the Southern Motorway from Takanini and on State Highway 2 to Coromandel.
Coming back on Monday, the busiest times are from midday to 7pm.
"If everyone plans their travel in advance, and thinks about how they can travel outside the busiest periods it will help reduce congestion, delays and stress and that will make it a safer and more enjoyable journey for everyone.
"The hot spot predictions have proved really popular in helping people make informed decisions about when to travel, but predicted peak times can change on the day because of incidents, changing weather and even driver behaviour. So keep up to date with real time travel information."
Roadworks south of Whangarei may also cause extra congestion for holiday-goers heading north for the weekend.
The roadworks at Oakleigh have already been a source of frustration for many motorists after reports of several hours of delays last Friday.
