Police have arrested a man after a spectator ran onto the race track at Upper Hutt's Trentham Racecourse during the Wellington Cup Day yesterday.
The man has been charged with criminal nuisance.
Footage circulating on social media shows the man jumping the fence and entering the track, forcing jockeys to steer their horses around him.
Jockeys were left trying to avoid the male offender as he stood in the middle of the track as the field fanned out directly in front of the main grandstand.
