Navigating logged up highways and slow-moving traffic could be tricky this Queen's Birthday Weekend.
But New Zealand Transport Agency's map pinpointing forecast congested hotspots may help holiday-goers avoid road rage.
Already, State Highway 1 north of Auckland is closed after a fatal crash near Te Hana.
NZTA senior journey manager Neil Walker said going online to plan the journey before getting on the road reduced the chance of experiencing delays on busy highways.
"This is the last long weekend for a few months and the last one before winter really sets in, so many people take the opportunity to head away for a break, or to visit friends and family," he said.
NZTA safety and environment spokesman Harry Wilson said it was important that people were patient and did the simple things: keep speed down, buckle everyone in and stay focused on the road.
As of yesterday, NZTA said 164 people had died on New Zealand roads this year.
After a fatal crash on State Highway 1, north of Wellsford, this morning, Mangawhai and Kaiwaka-Mangawhai Rds are closed and diversions are in place.
"Police will be out on the roads across the country working hard to keep everyone safe, but everyone needs to do their part," Wilson said.
