Traffic is at a stand-still along parts of Auckland's motorway network, with the beginning of the school holidays and bad weather contributing to delays for motorists.
Waka Kotahi NZTA's live traffic map shows traffic is crawling on the parts of the Southern Motorway, as congestion backs up heading south from Spaghetti Junction to Drury.
The Southwestern Motorway is also heavy from about the Waterview Tunnel to the interchange with the southern at Manukau.
A crash at the Waterview Tunnel southbound entrance blocked two lanes, with traffic backing up to St Lukes on the westbound Northwestern Motorway. It has now been cleared.
A crash on the right northbound lane after the Northcote on-ramp is also delayed travellers on the North Shore. It has now been cleared.
Further north, a crash near the intersection of Murdoch Crescent in Whangārei blocked the southbound lane. Waka Kotahi NZTA advised motorists to follow the directions of emergency services and expect delays in both directions. The crash has now been cleared.
Earlier, a crash on the Auckland Harbour Bridge blocked northbound lanes at 3.25pm. The crash was cleared at 3.40pm.
A breakdown at 3.55pm has blocked the middle northbound lane near the Hillsborough Rd off-ramp on the Southwestern Motorway. Waka Kotahi NZTA warns to expect delays.
At 3.40pm a crash blocked the right westbound lane on State Highway 16 just after the link to the SH20 Waterview Tunnel. It was cleared at 4pm.
A crash has also blocked the right northbound lane on SH1 just after the Highbrook Rd off-ramp. At 4.15pm, Waka Kotahi NZTA tweeted that the lane remained blocked.
A crash on the Southern Motorway about 3pm blocked a southbound lane just after the Redoubt Rd off-ramp.
Traffic on the Southern and Northwestern Motorways at Manukau is also heavy after a crash in the early afternoon blocked two northbound lanes just before the Lambie Rd off-ramp. It has since been cleared, but delays remain.
A serious crash on the Desert Road, State Highway 1 between Waiouru and Rangipo could also cause delays as emergency services respond.
The transport authority is warning motorcyclists and motorists in the South Island driving a caravan, campervan or any high-sided vehicle to take care in high winds between Springs Junction and Reefton, SH7.
In Wellington, a rockfall earlier in the day on a scenic route out of the city slowed some motorists down on SH59 at Pukerua Bay. The rockfall is now clear.
Also in Wellington, a slip on Remutaka Hill caused reduced speed limits temporarily between Upper Hutt and Featherston, but it has since cleared.
The exodus from the big cities for school holidays has begun – with motorists and families leaving work early and heading to holiday getaway spots.
While the weather for the first weekend of the holidays won't be that seasonal – rain and showers are forecast for a lot of the country – it hasn't stopped Kiwis heading away before the normal late afternoon/early evening rush hours.
And as travel begins, police and road safety advocates have urged everyone to drive to survive; with the holidays coming at the end of a September where eight people died in just a week.
The country's top road policing boss is urging drivers to be responsible to prevent serious crashes during the school holidays which start this weekend.
New Zealand director of road policing Superintendent Stephen Greally told the Herald the number of people losing their lives on roads was concerning and horrific.
"Most of these crashes are unnecessary. This is happening because some drivers are making poor decisions - speeding, using devices while driving and not wearing seat belts.
"It is heartbreaking when we have to knock on someone's door to inform them that their loved one has died in a car crash."
Safety was the only way to prevent future fatalities, Greally said.
"We will be out there making sure that all drivers follow the rules.
"We want people to drive responsibly and avoid making poor decisions.
"Drivers need to understand one bad decision can cost someone else their life."
As of yesterday, the Ministry of Transport has reported there have been 268 road deaths so far this year, up by 32 from last year's figure of 236.
According to the ministry's website, 28 people had lost their lives this month in fatal crashes on New Zealand's roads.
And just last week the Herald reported eight people died in crashes.
Students Against Dangerous Driving (Kaitiaki o Ara) general manager Donna Govorko is also asking motorists to take time to consider their responsibility and drive safely these school holidays.
"Help us all to get to our destination safe and alive," Govorko said.
"It is very disappointing to see that the number of people being killed or seriously injured on our roads keeps going up.
"What needs to happen to make people understand that we can do more as a community to turn this around? Many fatal and serious injury crashes are avoidable by making a few changes.
"Drive to the conditions, no distractions, safe speeds, drive sober, wear your seat belt."
Govorko said these were simple things motorists could do to be safer.
"The decisions we make don't just impact us they impact other road users and their families."
