Another friend, who wished only to known by his first name Woody, said he and Moat were "super close."
"She was a tough girl, she didn't let people push her around and she always spoke her mind.
"But she was awesome. It was always a good time with Freedom, never a dull moment," he said.
Moat had two kids - a boy aged about 5 and a girl a few years older. Woody said she was embroiled in a custody battle over the children, who didn't live with her in Christchurch.
"Rest in peace Freedom..." another friend, Michael Brodie, wrote on Facebook.
"You were so much fun to be around, and I will cherish the good times we had. Thanks for being such a good friend to me. Gonna miss you heaps."
The Serious Crash Unit is investigating the crash to determine the cause and the death will be referred to the Coroner.
