More severe weather is on the way for the upper North Island on the first day of May.

As the weather system moved south on Sunday night, the worst should be over for Northland.

In the Coromandel, MetService advised to expect 120-180mm of rain to fall, with 70-100mm nearer the coast until at least 5pm on Monday.

In the Bay of Plenty west of Kawerau, including Rotoru there could be 150-220mm of rain until 2am on Tuesday, with more heavy rain possibly ahead for Tuesday and Wednesday night.

In Tasman, northwest of Motueka, there is an orange heavy rain warning in place for the 24 hours between 3pm Monday and 3pm Tuesday, May 2.

MetService said to expect 100-140mm of rain with peak rates of 15-25 mm/h expected from Monday evening.

On Sunday, heavy rains caused a large slip on SH1 through the Dome Valley between Wellsford and Warkworth.

It was initially closed in both directions until northbound traffic was permitted to travel.

The southbound lane remained closed overnight with crews in place repairing the damage.

The Brynderwyn motorway at SH1 is expected to reopen at 6am Monday as scheduled.

Waka Kotahi crews were onsite Sunday to monitor the weather’s impacts on the road, which suffered from slips and underslips during Cyclone Gabrielle.
