Pop superstar Melanie Blatt of UK multi-platinum selling group the All Saints and breakout Kiwi singer-songwriter Ruby Frost will join Daniel Bedingfield and Stan Walker to complete the judging panel for TV3's The X Factor NZ.

Melanie Blatt co-founded All Saints in 1993, which quickly became one of the most successful British pop groups of the 1990s; with nine top ten singles including global hits 'Never Ever', 'I Know Where It's At' and 'Pure Shores,' the theme from Leonardo Di Caprio film The Beach. All Saints' album sales have eclipsed 10 million globally, and the group's music industry achievements include multiple BRIT Awards and MTV Europe Music Awards.

Ruby Frost is one of New Zealand's most talented rising pop stars. She captured the attention of the local music industry, and a recording contract in 2009, winning the inaugural MTV talent competition 42Unheard. In 2010, Ruby won the Grand Prize in the pop category of prestigious international John Lennon Songwriting Contest, with her hit song 'Hazy.' In the same year, she performed at iconic Hollywood venue, The Viper Room, two CMJ showcases in the United States, and at Big Sound festival in Brisbane. Her current single 'Young' is on rotation on NZ radio, including radio stations The Edge and MORE FM.

Melanie Blatt and her daughter will move to New Zealand for the duration of the highly anticipated TV3 series.

"I can't wait to see what kind of artists and voices we are going to find in New Zealand. I'm sure there is a wealth of untapped talent waiting to be found and nurtured," Melanie says."I also cannot wait to discover New Zealand properly. My daughter is a HUGE Lord of the Rings fan. We are beyond excited about living there for a bit."

Ruby Frost has experienced first-hand what the right opportunity can mean for success in the Kiwi music scene.

"I got my start in music through a live competition too, so I know what it's like to battle with nerves for a shot at your dream," she says.

"I just want to share what I've learnt over the past few years; about recording, working with labels and publishers, and breaking into the local scene."

Co-executive producer Andrew Szusterman says he could not be happier with the judging panel for The X Factor NZ.

"Between them Mel and Daniel have sold over 14 million albums worldwide. Stan and Ruby have singles rotating on radio right now, meaning we have a panel that knows how the music industry works, and what it takes to achieve chart success," he says.

"For New Zealand to have mentors of this calibre means we are on track to deliver a vibrant and fresh recording artist for the music industry."
