Prince Philip reportedly hasn't apologised to the woman whose wrist was broken when his Land Rover hit the vehicle she was travelling in.
Philip was unhurt in the accident, which happened on Friday (NZ time). A baby in the other vehicle, a Kia, was also unhurt.
But Emma Fairweather, 45, had her wrist broken.
"I'm lucky to be alive and he hasn't even said sorry," she told UK tabloid The Mirror.
"It has been such a traumatic and painful time and I would have expected more of the royal family."
Ms Fairweather said she hasn't even heard from the palace yet, let alone receive an apology.
"I know the Queen is a busy lady but I was really excited at the idea she might phone me. Instead, I got a call from a police family liaison officer.
"The message he passed on didn't even make sense. He said, 'The Queen and the Duke of Edinburgh would like to be remembered to you.' That's not an apology or even a well-wish."
She says her friend was driving well below the speed limit when the prince's vehicle came straight at them.
"I kept thinking he was going to stop but he didn't. It all went into slow motion as I watched the other car."
On hearing the other driver was none other than the Duke of Edinburgh, Ms Fairweather said she was shocked, confused, upset and overwhelmed.
Both drivers passed their breathalyser tests.
Buckingham Palace told The Mirror a "full message of support was sent to both the driver and the passenger", despite Ms Fairweather's complaints.
Philip earlier on Sunday (NZ time) was photographed back behind the wheel of a brand new Land Rover, appearing to not be wearing his seatbelt.
