"It was pretty terrifying seeing her just lying on the ground all blue."
Ms Bolt spent two weeks in hospital, the first two days in a coma, and woke up on her partner's birthday.
"I woke up on the Friday, on his birthday, so he was pretty happy about that, but I don't remember anything after the Saturday before I collapsed."
Now recovering at home and hoping to go back to work next month, Ms Bolt has to live with a defibrillator in her chest.
"It's there just in case it happens again, so if it does, the defibrillator will just kick-start her heart," her mother said.
Ms Bolt said the experience had made her more appreciative of life, which she planned to keep living to the full.
Mrs Bolt said Farmers had been supportive of the family.
"They've been really good, they put me and Alannah's dad, Neil, up at a motel in Wellington so we could be near her and we didn't have to worry about where we were going to stay," she said.
