Mr Leslie is competing in his fifth horse ploughing national final, while Mrs Rae will be competing in her first final.
A ploughman since an early age, Mr Leslie began horse ploughing five years ago, while Mrs Rae started in May last year.
Wanting to give it a go, she said to Mr Leslie if he ever needed a driver, to give her a bell.
When Mr Leslie's old partner hung up the reins, he got in touch with her, and the rest is history.
"I just love it," she said.
Mr Leslie, on the other hand is a contractor, but it was still quite the learning curve going from horsepower to horses, as well as going back to a single-furrow plough, he said.
He started out after some arm twisting from renowned horse ploughman Dave Murdoch, also of Middlemarch.
Nugget and Anna were Mr Murdoch's horses, and while Nugget had three finals under his belt, Anna was a rookie, competing for the first time at a national event.
Mrs Rae will drive the horses, while Mr Leslie will do the ploughing, with a Reid and Gray single furrow plough.
In preparation for the nationals, the team competed at Waimate and Palmerston ploughing matches at the weekend.
"It's a bit hard because the season is May to November, so you don't get a lot of practice in," Mr Leslie said.
Following back-to-back wins at the last two national finals for Mr Leslie, the pair had high hopes of winning again this year.
"That's the aim," Mrs Rae said.
The horse ploughing final will include two North Island teams, two from Canterbury and two from Otago-Southland.
The New Zealand Ploughing Championships are being held on a property on the Thornbury-Waimatuku Rd tomorrow and Sunday.
There are 20 competitors in the Silver Plough and Reversible classes, including seven from Otago-Southland.
They will be vying for two places to represent New Zealand at the world championships in Ohio next year.
Last year's FMG Young Farmer of the Year winner, Nigel Woodhead, from South Otago, will also be competing.
