One person has serious injuries after a two-vehicle crash closed State Highway 2 for an hour and a half south of Norsewood on Thursday.
Police were called to the accident near Blairgowrie Rd about 2.26pm.
An NZ Transport Agency (NZTA) social media post said all emergency services were attending, and delays were likely.
At 4.10pm, NZTA said the highway had reopened to one lane, with a “stop-go” system in place at the intersection of SH2 and Blairgowie Rd.
