Jockey Rebecca Black has died in a race fall at Gore in New Zealand.

The Riverton-based Black was riding Point Proven in the eighth race when the horse knuckled and fell near the 700m mark, New Zealand Racing says.

Misscattlecreek and rider Terry Moseley also crashed with Moseley emerging without major injury. Misscattlecreek had to be euthanised.

Black, a mother of three children, rode 108 winners during her career and was a well liked member of the southern racing community.

Racing Integrity Unit stipendiary stewards have opened and then adjourned an inquiry into the incident.

Police say they were called to Gore Racecourse about 4.10pm on Sunday.

They are preparing a report for the coroner and WorkSafe New Zealand have been advised.

The rest of the Tapanui Racing Club meeting, a Christmas event, was called off after the death.

Tributes are flowing for Black on social media.
