Police have warned motorists they would be out in force today in a crackdown on speeding, distracted and alcohol-fuelled drivers as holiday makers head home.
The long weekend got off to a bad start on the roads, with three deaths within the first 12 hours of the holiday period.
Another three people died as a result of crashes on Thursday before the start of the official road toll period.
Acting road policing national manager Inspector Nic Brown said today there would be a higher number of vehicles on the road and the distances that people were travelling would be further as they returned from their holiday destinations.
"We know people are going to make mistakes but the thing is, it shouldn't cost anybody their life or limb," Mr Brown said.
"The indication is with those three fatalities and I don't want to speculate on specific cases it does come back to your speed, whether you're wearing a restraint or not. It's really simple behaviour."
Last year's road Easter road toll was three, while there were no deaths in 2012. The highest recorded number of deaths was 21 in 1971.
As with other holiday periods, police have lowered their tolerance of speeding drivers to 4km/h, and Mr Brown encouraged drivers to watch their speed and give themselves time to react.
