Olivia Robertson won the Norwood Gold Cup at the Farmlands Horse of the Year Show in Hastings.
The 21-year-old full time rider steered her Gisborne bred horse Ngahiwi Cisco to a classy clear in the hotly-contested jump-off.
Seven of the 30 original combinations came back for the against the clock jump-off.
Robertson (Christchurch) was second to go on the 12-year-old gelding and set the stage with tight turns and a big gallop into the last, leaving everything up in 51.65 seconds.
No one could match her - several gave the time a good nudge, but paid for it with rails.
