Bernice Blackstock's lover, a new father-daughter duo and an old acquaintance of Rhona Goskirk have all been cast as fresh faces for the ITV1 soap.
First to arrive will be Rhona's wild friend from college Vanessa Woodfield, who has been tipped to shake up life at the vets' surgery.
Played by The Royal actress Michelle Hardwick, Vanessa is billed as a "self-assured party girl" who will be "like a breath of fresh air" when she arrives at the vets' practice.

While Vanessa is always up for a laugh, she is also plain-speaking and instantly clashes with Rhona's husband Paddy.
Hardwick commented: "As a local girl and a fan of the show, Emmerdale is my dream job. After only two days, I am starting to feel at home already and Vanessa is such a fun character. I can't wait to see what's in store for her."
Next to turn up in the Dales is Bernice's charismatic lover Steve Harland, portrayed by Scottish-born actor Tom Mannion.
Show chiefs have said that Steve is a passionate and optimistic man, but "the qualities that attracted him to Bernice - her energy, spontaneity and quirkiness - may be the very things that end up driving him mad".
Mannion enthused: "I'm really looking forward to the adventure that is Emmerdale."

Meanwhile, mechanic Dominic Andrews and his wayward teenage daughter Gemma are also on the way to Emmerdale.
Waking The Dead actor Wil Johnson has been cast as Dominic, who is still finding his feet as a single dad. Gemma, meanwhile, is played by 14-year-old Tendai Rinomhota.
Johnson said: "I can't wait to get started. I am looking forward to an exciting journey. I've been told anything could happen with my character."
Emmerdale's series producer Stuart Blackburn added: "It's an exciting new season for Emmerdale and we are delighted to welcome Michelle, Tom, Wil and Tendai to the cast."
Hardwick and Mannion have already filmed their first scenes, while Johnson and Rinomhota begin shooting within the next few weeks.
