Two people have been choppered to hospital in a serious condition after a bus rolled near Queenstown, blocking the road and leaving 20 people injured.
Two others passengers on the bus were taken to hospital to be treated for less serious injuries, Inspector Olaf Jensen, Otago Lakes Area Commander said.
The Glenorchy-Queenstown Road was closed while heavy lifting equipment moved the tipped bus but reopened just after 8pm.
The crash occurred on Glenorchy-Queenstown Rd about 7km southwest of Queenstown. The bus came to rest on its side.
More than 20 people had been on the bus, all foreign nationals, Jensen said.
