Traffic hell threatens to sour the end of the holidays for many New Zealanders - but data from last summer can help predict the best time to brave the journey back home.
Those wanting to avoid some of that pain should pack up the car and kids and hit the roads as early or late as possible, as information from last year's holiday period shows some of the country's key routes will be chocka most of the day tomorrow.
The NZTA has released a Holiday Planner, that uses information from last year to predict the best - and worst - time to brave the commute home.
Green indicates free-flowing traffic, orange shows "busy" and red "heaviest" congestion. During daytime hours, some of the main holiday routes are predicted to be largely in orange and red tomorrow.
Journeys will be easier today, but traffic is still expected on many routes.
NZTA says the predictions are subject to change based on weather and other factors like crashes, and commuters should also check its Journey Planner tool for real-time information. Below are the Holiday Planner predictions for today and tomorrow.
People driving State Highway 1 south from Whangārei will hit "busy" traffic from about 9.30am until 2pm, with heaviest congestion from 10.30am until around 12.30pm.
The notorious section between Wellsford and Puhoi will be busy most of the day - from around 9.30am until 4pm, and in the "red zone" of heaviest traffic from about 10.30am until 3.30pm.
