In the three images released of the new campaign, Miranda shows off her yoga toned body as she showcases the brand's latest range of lingerie.
In one shot, the Australian beauty models a red set of sporty separates, accessorising with a silver bangle and gold chain necklace.
The model ended her contract with the rival lingerie brand back in April of last year, citing her son Flyn, three, as the reason for her departure.
"I have felt this coming since my son was born and, after I became a mother, I realised I needed to prioritise my time," she told the Sydney Morning Herald.
Since leaving the company, Miranda has fronted several campaigns for high profile brands. She is the face of high street retailer H&M and in October of last year, she was named the face of Austrian crystal house Swarovski for their autumn/winter campaign.
By signing with Wonderbra, the mum-of-one, 30, follows in the footsteps of supermodel Eva Herzigova, who shot to fame after appearing in the brand's iconic 'Hello Boys' campaign in 2004.
Miranda split from her moviestar husband Orlando Bloom at the end of last year after three years of marriage.
But she bumped into her estranged husband at one of Hollywood's Oscars after-parties last week.
Stunning in a figure-hugging metallic dress with a deep plunging neckline, Miranda first saw her ex on the red carpet of the Vanity Fair after-party – when she was mid-interview with a TV crew.
Orlando, 37, didn't hesitate in greeting the Australian model and mother of his three-year-old son Flynn, from whom he split at the end of last year after three years of marriage.
"Hi. You look amazing," said the British Hobbit star as he gave her a peck on the cheek. He then asked if she was doing well, to which a surprised Miranda replied, "Yes."
