Auckland and Wellington were the worst regions hit with traffic delays after crashes hampered holiday-makers' getaways.
A crash on the Auckland Harbour Bridge partially blocked the right lane on the northbound. Motorists were backed up to Wellington St.
A person crossing the Harbour Bridge told the Herald he had seen multiple crashes on SH1 near the bridge, and in both directions. One of these was a three-vehicle crash in Mt Wellington around 11.30am northbound on the southern motorway. Two lanes were blocked but were cleared within an hour.
"One of them likely have caused injury of a motorcycle driver, police and ambulance are at scene, providing emergency treatment."
