The four-year-old daughter of Rip Van Winkle has had six starts this season, notching up three wins and recording two third placings.
Two of her wins have come in New Zealand Bloodstock Insurance Pearl Series bonus races, something Didham said was targeted from the outset.
Fairlight's first start from the Didham stable came at the New Zealand Cup meeting in November and expectations were high.
"Even though she drew 18 of 18 we expected her to run well," Didham said.
"Mark du Plessis rode her and they finished sixth. He got off and said she was a nice horse and would probably win a few races - she won her next two."
Leading into today's black type assignment on her home track, Didham said he couldn't be happier with Fairlight.
"Her races have been well spaced and she has done everything right," he said.
"She is thriving and we are definitely hoping for a good run."
