West Auckland motorists are being told to expect "heavier than usual" traffic heading into town after a number of crashes on the main motorway this morning.
A crash between Great North and St Lukes Rds on the Northwestern Motorway blocked the right lane, citybound, from 6.30am.
The area was cleared just before 7.30am but is still heavily congested.
The NZ Transport Agency is telling people to drive with care, delay travel times or expect delays on the commute this morning.
"Allow extra time with SH16 heavier-than-usual this morning," NZTA said.
