The Mission Estate Winery Concert will be renamed after "an embarrassing mistake", says the event director.
Irish musicians Ronan Keating and Sharon Corr were branded as Brits after being billed as part of The Mission's UK Invasion Concert in February, which upset Hawke's Bay's Irish community.
Joe Kelly, of Taradale, said it was a sensitive issue.
"Men lost their lives trying to be Irish and remove the yoke of British imperialism and now they are not recognised," he said.
Antoinette Earl, of Hastings, said it was "just cheap, slack marketing".
