Raducanu suffered fewer injury problems last season, but only played 10 matches after Wimbledon, and also missed March's Miami Open with a back issue.

She has hired the renowned fitness trainer Yutaka Nakamura, who has been in Auckland with her.

"I just needed a more tailored approach and I needed someone more dedicated to me alone as an individual and I'm looking forward to what comes with this," Raducanu told reporters earlier this month.

"It definitely adds another dimension to the way me and [coach] Nick [Cavaday] work," she added.

"It's all become, in a very positive way, integrated and together and connected, and we can see already things transfer on to the tennis court that we do in the gym."

Raducanu is currently ranked 56th in the world and so will not be seeded for the Australian Open.
