She has spent most of her life training domestic animals of all descriptions, and believes this helped her be a better mum to her 4-year-old son.
"When training a horse, you cannot reward them for good behaviour, unless you first notice the good behaviour. So reward-based training is all about practising mindfulness and gratitude. In order to be good animal trainers, we have to train ourselves to notice and acknowledge the good things that are happening all around us. This naturally spills over into our wider lives and becomes a cornerstone habit."
Harrison said there were lots of opportunities for young people to take part in mainstream competitive events but "our vision is to create a place where they can focus on the foundations of their communication with their horses".
"This means that if they choose to continue into traditional competitive environments, they will have a happy and willing partnership with their horse."
The Mane Priority has been well received, with 13 teenagers registering in the first 24 hours. Prize sponsors and supporters have also come on board.
The event will be held at the Tauranga RDA on Sunday, September 16 and the next event is planned for later this year.
