"Many crashes occur when drivers are driving too fast for the conditions and lose control on bends, especially in small rural communities," Mr Hodson said.
"Northland has a lot of narrow windy gravel roads in these rural areas, which are not very forgiving when a driver loses control of their vehicle."
Police will be holding checkpoints throughout Labour Weekend, along with mobile, random stops - every driver who is stopped will be breath tested.
Mr Hodson said other road users also have a part to play. "Remember, please call *555 if you see any poor driving and we will act on it immediately if there is a patrol car in the area, or follow up later.
"Travelling is a journey. It's not about the destination, so enjoy the drive."
Whangarei Fire Safety Officer Craig Bain said people need to check smoke alarms in their holiday homes and have spare batteries in case they need replacing.
In caravans and campers, smoke alarms can be on velcro dots, so people can put them back after cooking in those confined spaces where alarms are easily activated by cooking.
"Check the electrical warrant of fitness and ensure all gas connections have no leaks," Mr Bain said.
As this is the weekend people usually get out the barbecue, it's a good opportunity to check all the gas lines for signs of wear and tear, too, he said.
"Connect up your bottle and rub dish detergent around the connections. Turn on the gas and if it bubbles anywhere you have a leak, so get it fixed."
Maintenance includes cleaning out any fats and oils accumulated from last season, and always shut the gas barbecue off at the bottle when finished.
