But ahead of the upcoming RBS 6 Nations campaign, where Wales will be defending their Grand Slam in the absence of head coach Warren Gatland, defensive coach Edwards has cut short his time with Irish.
Edwards was part of the 2009 British and Irish Lions coaching set-up in South Africa but has been overlooked by Gatland for this summer's trip to Australia.
But with the RBS 6 Nations getting underway next month the former rugby league star will be linking up with Rob Howley to mastermind Wales' campaign.
"After consultation with Roger Lewis, CEO of the WRU, I am to concentrate solely on Welsh rugby in the build-up to Rugby World Cup 2015," Edwards said.
"Thus my consultancy work will cease with immediate effect."
