Racing: Gingernuts flies NZ flag

Gingernuts has made an immediate impression in Australia by becoming the fourth New Zealand-trained horse in seven years to win the group one Rosehill Guineas.

The New Zealand Derby winner made his Australian debut in yesterday's 2000m race for three-year-olds at Rosehill and upstaged the locals in the heavy conditions to continue his rise.

Gingernuts defeated favourite Inference by 2 lengths, joining Jimmy Choux (2011), It's A Dundeel (2013) and Volkstok'n'barrell (2015) as recent New Zealand-trained winners of the race.

The Stephen Autridge and Jamie Richards-trained gelding needs to be a late entry for the Australian Derby but Richards confirmed the intention to run in the 2400m classic at Randwick in two weeks, with Gingernuts now $4.60 favourite.

"He's going to be awfully hard to beat in a couple of weeks' time," Richards said.

Richards felt Gingernuts had kept improving since the NZ Derby (2400m) and the drop in distance to 2000m yesterday was countered by the testing conditions.

"It's a huge buzz. I'm really pleased for the team at home," Richards said.

"David [Ellis] bought the horse at the ready to run sales and didn't pay a lot for him and we syndicated him amongst some clients of ours and they're having a whirlwind ride."

Gingernuts carries the colours of Ellis' Te Akau Stud and Ellis is the managing owner of a syndicate which race the gelding.

Jockey Opie Bosson settled Gingernuts back before making his run around the field from the 800m.

Gingernuts reeled in leader Harper's Choice just inside the final 200m and despite tiring late had a comfortable margin over Inference with So Si Bon ($20) another short half-head away third.
