A large underslip on State Highway 2 between Ōpōtiki and Gisborne has reduced the road to one lane.
Waka Kotahi New Zealand Transport Agency said contractors discovered a large underslip on the road early this morning, following heavy rain in the area for the past 48 hours.
An urgent inspection of the site is being undertaken this morning, and a full closure of the highway in both directions may be necessary.
State Highway 2 has been reduced to a single lane on the southern approach to the Motu Bridge between Gisborne and Ōpōtiki.
