As Constable Gary Prescott battled to save an elderly woman from drowning in her car in a Christchurch drainage canal, she told him that she would be fine to "drive home from here".
"It took some coaxing to even get her hands to unclench from the steering wheel. I don't think she really realised where she was and what had happened," the police officer of 11 years said.
With the water above his waist and the car sinking in front of him, Mr Prescott knew he had to get the woman, aged in her late 70s or early 80s, out of the vehicle before it submerged, but in her confused state she was struggling against him.
His persistence in getting her to safety has earned the Christchurch policeman, 48, a Commissioner's Commendation.
His award citation says his "bravery and diligence was in keeping with the highest traditions of the New Zealand police".
