"She was in a deep hole so they carried her up a pathway to an observation point.
"From there we winched her up in the stretcher with a paramedic."
Mr Kowalski said it was a "pretty full-on" rescue because he had to hover the helicopter among trees while winching the patient and the paramedic.
The woman was flown to Rotorua Hospital, where she was treated for lower spinal injuries.
Also yesterday, the Westpac rescue helicopter was called to the Kauaeranga Valley on the Coromandel Peninsula to help a canyoner who had fallen 6m on to rocks.
The man was flown to Auckland City Hospital with serious injuries.
