Heavy-fog warning to motorists
Emergency services have been called to two crashes in the region today as thick, low-lying fog made driving difficult.
Firefighters were called to the intersection of Fernside and Townsend roads, just south of Rangiora, about 7.30am after two cars collided.
People had been taken to Christchurch Hospital with minor injuries, but it was not yet known how many were hurt.
Two people were injured in a one-car crash near Tekapo.
The 7.20am crash was on the Tekapo-Twizel road. The injured were taken to Timaru Hospital.
MetService duty forecaster Michael O'Connor said Christchurch's early-morning fog was typical for this time of year.
Moisture and still conditions in the region contributed to the thick mist that could linger all day, he said.
The skies were expected to clear today by mid-morning.
A police spokesman said motorists should "take things a bit more carefully and quieter".
"People should drive to the conditions, as we always say," he said.
Christchurch Airport spokeswoman Yvonne Densem said no flights had been affected by the fog.
Light fog had drifted over the airport briefly but it was sunny and claer by 8.30am.
