Part of State Highway 1 in Hamilton was closed this morning for emergency repairs after a tomo or sinkhole caused by a broken stormwater line opened up.
The tomo appeared near the centreline of Lorne St near the Dowding St intersection, not far from Waikato Hospital.
Waka Kotahi NZ Transport Agency initially closed the road in both directions to allow work crews to assess the damage.
