Then in June this year, Tolra was just metres from his home after being out jogging when he collapsed from a second cardiac arrest.
Emergency department nurse Joby Paul was driving down Western Hills Drive when she noticed Tolra lying on the ground being attended to by someone. She stopped to help.
Midwife Priscilla Ford also pulled over with her home birth kit which included oxygen, and the pair worked together to perform expert cardiopulmonary resuscitation (CPR) on Tolra until an ambulance arrived.
Neither Paul nor Ford were aware the other was a health professional, but Ford recalls thinking Paul must have listened to her instructor during first aid training because she was performing textbook CPR.
Together their skills saved Tolra's life.
Kaye Tolra was at work when she got a call from ED asking her if she was Norman's wife. They had found a set of keys on him which had his NHI number slotted into the key ring.
Tolra was airlifted to Auckland Hospital where he spent a week in intensive care, followed by two weeks back at Whangarei Hospital recovering from both the cardiac arrest and a head injury from his fall to the ground.
His wife said she didn't know what the protocol was when meeting someone who had saved your husband's life.
''We can't do anything more than say thank you to Priscilla and Joby, and live our lives in a way that gives thanks.''
All four urge the public to consider learning CPR, which when performed early is the most critical factor in a patient surviving. St John and Red Cross offer regular first aid training for members of the public.
Kaye Tolra said the couple have taken several lessons away from the incident but, above all, to be thankful for every day.
She will be ''paying it forward'' by travelling to Vietnam at the end of the month to volunteer in a psychiatric hospital. This will be her second trip to the Qui Nhon hospital.
Her husband will go with her and when her hospital work is over they plan to take a well-deserved break to see more of the country.
