Motorists heading into Auckland city are advised to expect delays following a single vehicle crash on the Southern Motorway.
One person has been taken to hospital in a serious condition.
Waka Kotahi NZTA said all lanes were open at 2.25pm, but that motorists could continue to expect delays.
Meanwhile, another crash on the southwestern motorway partially blocked the right southbound lane between Walmsley Rd off-ramp and Walmsley Rd on-ramp earlier this afternoon, but Waka Kotahi advised all lanes were now open.
But motorists have been advised there could still be some delays.
Further south, traffic is flowing well through Hamilton except for a slow patch around Taupiri.
And there are pockets of slow traffic in central Wellington.
The place to be on the roads this afternoon, is the South Island, where there are no major headaches for motorists.
