Two people are fighting for their lives after a collision between a car and a truck closed a road in Waikato.
State Highway 27 is closed at Waharoa following a serious crash.
Emergency services were called to the crash involving a truck and a car at 8.45pm.

Further north fallen power lines closed a road near Kaikohe tonight.
Northland Police said on Facebook that Ngapipito Rd is closed between Moerewa and Kaikohe after a car hit a power pole.
The car and driver left the scene without calling emergency services, the post read.
"I hope he or she reflects on the danger they left our community to face tonight.
"There are power lines on the road. Top Energy staff are working on site now."
It was expected that the road will be closed until about midnight.
"If you need to travel between Moerewa and Kaikohe please use SH1," the post read.
Earlier today a two-car crash in Kumeu closed a section of Old North Road causing diversions.

State Highway One is closed south of Ward in Marlborough following a truck crash.
Police were notified a truck had rolled at about 9.40pm.
"The driver wasn't injured," police say.

"This could take some time and there are no diversions available."
