A section of State Highway 30 in the Bay of Plenty will be closed today while police investigate a crash that happened on Friday.

The two-vehicle crash happened near Braemar Road, which injured eight people and critically injured one.

'SH30 will be closed and a detour will be in place between Rotoma and Te Teko between 9.30am to 1pm,” says the NZTA.
