Aucklanders are being warned of travel delays as car crashes on Auckland motorways are adding to school holiday and Friday traffic woes.
Waka Kotahi NZ transport Agency says traffic is building around the city and motorists need to allow more time for travel or delay their journey.
A crash near the Waterview Tunnel, near Point Chevalier, blocked lanes for over an hour on Friday afternoon.
St Johns said they were alerted to the incident at 1:28pm and two ambulances and a manager responded.
They said one patient was treated and transported to Auckland City Hospital in a critical condition.
A police spokesperson said their condition has now been degraded.
"Another person is speaking with police. The northbound lanes are likely to be closed for some time and motorists are advised to avoid the area and expect delays."
Northbound lanes were blocked during the incident, but the tunnel has since been cleared, Waka Kotahi said.
Another crash occurred on Friday afternoon on the Southern motorway near the South Eastern Highway off-ramp blocking the right southbound lane.
"Expect delays as congestion eases," NZTA said.
Earlier on Friday, Waka Kotahi NZTA warned the start of the school holidays was expected to have an impact on northbound traffic leaving Auckland.
"Friday usually has the busiest afternoon peak period of the week as people finish work early or head off for the weekend," general manager transport services Brett Gliddon said.
"The evening peak usually starts around 2:30pm but we expect today it will be earlier and heavier, with traffic beginning to build from midday."
Gliddon said the Harbour Bridge is still not fully operational with only three lanes open in each direction.
"We advise people going on holiday to consider delaying their journey until after the evening peak or even waiting until tomorrow morning."
