An increase in reported rape cases has Whangarei Rape Crisis workers warning women of all ages not to walk home alone at night and to make sensible choices about social behaviour.
Northland Police criminal investigations manager Detective Inspector Kevin Burke is also warning women to stay alert to their surrounding environment, keep an eye on their drinks in social situations, not accept unsolicited drinks and look after their friends while out partying or at licensed premises.
"If you are out with a group, stay with the group," Mr Burke said.
Anyone who is the victim of a rape that may involve spiked drinks should report it to the police as soon as they can because the cocktail of drugs only stays in the system for a short while, he says.
However, the police had not dealt with more rapes and sexual assaults than they would normally see and there was little indication drink-spiking was a factor in recent cases, Mr Burke said.
