The hearing for the apprentice jockey charged with careless riding in the race in which fellow jockey Megan Taylor was killed will be held on Tuesday morning.
On 15 December at Canterbury's Ashburton Raceway, a collision between several horses during a race resulted in Taylor falling off her horse.
The 23 year old died of her injuries later on the same day.
Karen Parsons, who trained Red Orchid, the horse Taylor was riding, told RNZ four horses had fallen during the race.
In January, the Racing Integrity Board charged an apprentice jockey with riding carelessly.
The hearing is being held at Addington Raceway in Christchurch.
