A logging truck and school bus have collided near Invercargill, in the second such crash in just over a week.
No children were on the bus and both drivers were unhurt.
Police were called to the crash at the intersection of Kennington-Roslyn Bush Rd and the Lorneville-Dacre Highway, about 10km northeast of Invercargill at about 3.50pm, Senior Sergeant Dave Raynes of Invercargill police said.
Police were still at the scene and traffic was being diverted.
"The most important thing if there's no injuries is just to get the vehicles marked and then towed away off the road, to unblock the road,'' Mr Raynes said.
The crash comes after 35 children were hurt when a logging truck collided with a school bus in Bay of Plenty last week.
An eight-year-old girl remains in intensive care at Auckland's Starship Hospital, while two 12-year-old boys and a 10-year-old girl remain in Tauranga Hospital in stable conditions.
