This is the first time the channel has run the awards ceremony in the UK.
The agency will report to comms director Reeta Bhatiani, who said she was looking for a consultancy with ‘expertise in the kids' market', as well as experience of event PR and ‘talent management.'
The awards have been running internationally for 20 years. The US version will take place on 31 March. They are hosted by Justin Timberlake, with guests including Beyoncé and Mike Myers.
A date for the UK awards has yet to be finalised. The channel said it hoped to hold pitches for the project during the next couple of months.
Viacom-owned Nickelodeon UK retains Frank PR for its consumer activity.
Frank is unaffected by the review.
