Auckland Westpac Rescue Helicopters performed five rescues in a week in Mahurangi this month.
A crew assisted a woman in her seventies on Kawau Island, who had fallen into a water tank while cleaning it.
Along with the fire brigade, they helped pull her out and flew her to North Shore Hospital.
On Waitangi Day, a crew rescued a man in his sixties in Mangawhai who fell 3.5 metres off a deck.
They also attended to a man in Omaha involved in a scooter accident. During the weekend, crew assisted a male patient aboard a large vessel near Little Barrier Island.
He was extracted with a winch and flown to hospital in a critical condition. A man from Wellsford was also flown to Auckland suffering a medical emergency.
