Mrs MacDonald was born into a large family and was one of five sisters and two brothers who grew up on a farm near Wairoa.
Her eldest child, Johnny Mohlmann, said his mother was "a huge success" and recalled fond memories of her 70th birthday in August last year.
Speaking at her funeral on January 3, he said his mum enjoyed a "mischievous spirit", was young at heart and a "bit of a thrillseeker".
"She liked fast cars and she was always telling me when I was driving her to 'boot it son'."
The grandmother of seven and great-grandmother of two "loved" her jet boating, skydiving and also swam with the sharks at the National Aquarium in Napier.
Rangi declined to comment following her court appearance in Napier on January 6. She is due to reappear in court in April.
