Dannevirke High School student Rebecca Aplin will represent New Zealand at the Christchurch Royal Show in November.
The Year 12 student has been named in the Royal Agricultural Society equestrian youth squad to defend the show-riding title won by the New Zealand team in Britain last year.
Aplin is no stranger to success, having won many national show-riding titles.
In Christchurch the focus will be on the rider, with horses and ponies assigned to the British, Australian and New Zealand riders dependent on the riders' size.
The inaugural 2016 team challenge was hosted by Britain's National Pony Society, where squad members on supplied mounts competed in ridden and led events designed by the host society.
Riders have three days to learn their mounts.
Youth squad members from each participating country are assessed on knowledge, understanding and skills with horses as well as their own interpersonal and team-building skills.
Proud Mum Viv Aplin said the squads would tour New Zealand equestrian facilities and take part in workshops.
"She is really looking forward to it," Ms Aplin said.
"She's rapt - she is representing her country."
Aplin will continue with show riding, which is limited to riders aged 14 years to 25 years, and hopes to become an equine physiotherapist.
At the Royal Show in Christchurch youth squad members will be assessed on:
High level of knowledge, understanding and skills in showing horses & ponies.
High level of knowledge, understanding and skills in managing ponies and horses.
High level of knowledge, understanding and skills relating to the equestrian breeds used as mounts in showing within New Zealand Australia and Britain.
