Fraser left the wheelchair to charge overnight in the driveway just outside the door, as usual.
She reported the theft to police, who she said were investigating. Whangarei police confirmed the electric wheelchair was reported stolen.
"They just told me they would keep an eye out," Fraser said.
She had no idea why anyone would want to steal the wheelchair: "They have no use for it."
Disability advocate Jonny Wilkinson said although the wheelchairs could cost a lot, they were customised for individual users and there was no way thieves could sell them.
"It takes away users' independence and it takes a while to replace."
Fraser said she doesn't know what will happen next or whether she is able to get a replacement wheelchair.
"I'm getting everyone to see," she said. She was unsure if insurance would cover it, or if it would be possible to get funding for a replacement.
Fraser has received an outpouring of support on social media after posting about the missing wheelchair. The post has been shared nearly 500 times.
Wilkinson said it was uncommon for wheelchairs to be stolen.
"You wouldn't be able to sell them on the black market."
The only other case he heard of recently was in the Bay of Islands last year, when Paralympian sailor Chris Sharp's wheelchair was taken. It was later returned to a Northland police station.
Fraser had just one message for the thieves: "Give it back".
