As a caregiver, she had some medical training and was concerned about the effect stress and shock could have on the pair.
A nurse from the Gonville Medical Centre checked on the woman but didn't take her blood pressure, she said.
Ms Munden cycled to the ambulance centre, saw other ambulances in the garage and couldn't understand why they weren't being used.
She was told a number of calls had come in at the same time.
Mr Seville said the woman was assessed by the emergency communications call-taker, and it was from there they got their instructions.
If the situation had been life-threatening, something would have been done, he said. In this case, the woman had a sprained ankle.
On the day in question, one of their ambulances was attending a fatal forestry accident on Tokomaru West Rd and a surge in calls meant the second ambulance attended about six call-outs during the period the woman at Gonville was waiting.
