Emergency service workers have commended the organisers of a New Year's festival for their first aid planning after a rescue helicopter was called for two drug overdose cases.
The Northland Electricity rescue helicopter was called to Mangawhai music festival Northern Bass at 11.15pm on Tuesday after there were reports of two people in critical condition as a result of drug overdoses.
A first aid crew at the scene hired by the event organisers dealt with the patients initially before calling the rescue chopper.
Intensive care paramedic Scott Mears said by the time the helicopter arrived the people - both in their 20s - were no longer in critical condition.
Instead, rescue helicopter medics took another man, also in his 20s, to Whangarei Hospital with a dislocated shoulder.
