Busy day for emergency services
Emergency services were kept busy on Tuesday attending serious incidents across Hawke's Bay.
A NZ Police spokeswoman said a vehicle had allegedly been stolen from a Flaxmere address early this morning before it was located and then stopped by police about 10.30am.
"Police located it and successfully deployed spikes on Wall St in Hastings," she said.
A 21-year-old man was arrested and charged with unlawfully taking a motor vehicle, driving in a dangerous manner and being an unlicensed driver failed to comply with a prohibition.
He is due to appear in the Hastings District Court on January 7.
A 32-year-old man was also arrested on an outstanding warrant.
Not long after that incident, a motorcycle rider came of their bike about 11.50am on Porangahau Rd, near Porangahau, in southern Hawke's Bay.
Paramedics and a rescue helicopter went to the scene and treated the rider who suffered moderate injuries.
The patient was flown to Hawke's Bay Hospital.
Emergency services were then called to the beach at Porangahau about 1.30pm following reports of two swimmers in trouble in the water.
A Hawke's Bay Rescue Helicopter spokesman said when they arrived the two swimmers - a father and son - had managed to get to dry land.
They were flown to hospital as a precaution.
