"I woke on the grass outside Rotorua Boys' High School near a power pole with my bike on top of me, I found my cellphone in my pocket and rung 111," Mrs Coppard said.
She struggled to describe where she was to the person taking her call.
"A lady crossed the street and I handed her the phone and she told the ambulance exactly where we were," she said.
"A few seconds later two cars pulled up on the side of the road and four other people came to help me, they rung my boss, as I was in my work uniform, and also my mum."
Mrs Coppard was taken to Rotorua Hospital where they told her the date.
"For some reason I thought it was March. I actually got married the week before the accident and couldn't remember any of that until someone told me what the date was."
Some of the theories about what happened include Mrs Coppard being hit by a car or riding into the power pole. She suffered severe bruising on her neck, back, shoulder blades and tail bone, as well as concussion.
"I don't know who the people were that helped me but I want to thank them," she said.
"A lot of people are thinking about Christmas and money and presents and I find it pretty amazing that they could still notice someone who needed help.
"There are still people with kind hearts out there."
Mrs Coppard, who is under doctor's orders not to return to work until the New Year, said she wanted to thank the strangers who helped her.
"I still do not know what happened and no one has come forward to say what had happened, and I still do not know who my rescuers were.
"I now look at my bike that is very beaten up and wonder what happened on that morning."
