Former Taranaki mare Twoznotenough is making the most of her opportunities in the South Island.

The Sakhee's Secret mare won five races for New Plymouth trainer and part-owner Allan Sharrock before she was sent to the Riccarton stable of Les Didham.

"I had her dead right for the Taranaki Cup and she ran fourth and a while after that I said to the other owners let's send her south," Sharrock said. "She's a good mare and very genuine."

Twoznotenough made an immediate impact from her new quarters with success at Riverton and on Saturday she produced a slick front-running performance to win the Listed Speight's Mid Ale Great Easter Stakes.

"She's got black type now and she's out of a Royal Academy mare so she's going to end up quite a valuable broodmare," Sharrock said.

Twoznotenough was well-rated in front by Leah Hemi after they jumped smartly to cross the field from the outside gate.

Hemi kicked the mare clear 300 metres from home they went to the line with three-quarters of a length to spare.

"She was getting a fair bit of weight so she was always going to be a decent chance," Sharrock said.

The topweight Maybe Miami fought valiantly under his 60kg, but found the effort of giving the winner seven kilos beyond him.

Meursault made ground from the tail of the field to take third with the favourite Ringo a battling fourth. He was trapped three wide without cover and was unable to make any impression in the run home.
