Kiwis are urged to keep safe this Easter weekend with heavy traffic warnings in place.
The holiday period runs from 4pm April 13 to 6am April 18.
New Zealand Transport Agency said travellers should expect a busy weekend on the roads as Easter coincides with the start of school holidays.
Transport Agency Auckland and Northland highway manager Brett Gliddon said he knew NZTA would see large numbers heading out of the main centres to their usual holiday destinations, which made queues and delays inevitable.
Heading out of Auckland, the traffic will start to build on SH1 in both directions from mid-morning on Thursday right through to about 8pm.
Gliddon said it was likely to remain heavy for much of the day on Friday, especially between Puhoi and Wellsford, on the Southern Motorway from Takanini, and on State Highway 2 to Coromandel.
"The hot spot predictions, which are based on previous holiday data have proved really popular in helping people make informed decisions about when to travel, but these should also be used alongside real time travel information."
The highway manager said teams would be monitoring traffic flows on the state highway network throughout the holiday period to provide up to date information on congested routes.
Police are also urging New Zealanders to take care, at home and away.
