'Year of excitement' as Grainne Seoige's RTE contract ends
However, a spokesperson for the TV host said she is still "open to doing contracted work" with the national broadcaster.
RTE will continue to employ Seoige but on a "programme by programme" basis.
Speaking about her TV career last year, Seoige said: "It's about finding the right thing for me in television.
"It's not about finding just the next thing. I'm very calm, very positive and, most of all, very excited about the future."
The Spiddal woman has been one of RTE's most popular presenters for more than a decade, fronting a variety of programmes including chat show Seoige and O'Shea, Seoige and The All Ireland Talent Show.
She previously worked for Sky and moved to London in 2010 to present ITV's morning show Daybreak.
In 2011, she returned to Ireland and hosted Grainne Seoige's Modern Life, the sports quiz Put Them Under Pressure, Up For The Match and the People Of The Year Awards.
She hosted Crimecall from 2011.
However, it was announced in September that she would no longer host the show.
In October, RTE said she had given up TV to pursue her career as a diamond dealer. Seoige said this was "not true", adding that she still had a contract with the broadcaster. RTE later retracted the statement.
"If I had a diamond for every time it was written that I'd been axed by RTE, I'd have more jewellery than Elizabeth Taylor ever owned," she said.
Seoige, who is engaged to rugby coach Leon Jordaan, will next appear in The Restaurant, TV3's new cookery show.
She is also working on her diamond business, Grace Diamonds.
"It has been a year of great excitement for me," she said. "I'm doing something new after 20 years of television".
