Prizes include the Bruce Forbes team trophy for best overall team, the Fred McKinstry Memorial Cup for best individual dressage, the Hodder Cup for best pre-training individual score, and the Burkhart Tray for best training individual score.
Mrs Johnson said the North Wairarapa Pony Club were the present holders of the Bruce Forbestrophy and have entered again to defend their title.
She said the South wairarapa Pony Club does not have a competitive side at the event this year, which was held at the Solway Showgrounds last year.
"We are organising the event this time around though but we don't have a competitive side.
"It's just how it works sometimes. Hopefully, next year or the year after."
