Gridlock traffic is likely to cause delays for Kiwis heading home from their summer holiday on Sunday.
State Highway 1 between Puhoi and Wellsford is expected to be jammed with cars. The NZ Transport Agency's (NZTA) holiday journey tracker shows there will be heavy traffic on the southbound route between 11am and 8pm.
"Road users are advised to expect delays and allow extra time when travelling through this area," NZTA says.
In the South Island, people leaving Saturday's Bay Dreams music festival in Nelson will likely contribute to congestion. The NZTA is anticipating heavy traffic on SH6 at Murchison between midday and 2pm.
Motorists heading into Christchurch from the south should also prepare for traffic, with roads expected to be at their worst between 11:30am and 6pm.
NZTA system manager Mark Owen told Newshub on Saturday that people need to plan ahead.
"We don't want anyone doing any necessary overtaking when everyone's trying to get home to their destination," he said.
Drivers across the country are being urged to be patient and travel early or later in the day. Click here for the full list of congestion hotspots.
