Prime Minister John Key has been confronted by "frustrated fans," voicing their annoyance at the last minute barring of hip-hop group Odd Future from New Zealand.
Members of the Los Angeles-based group, who were meant to be supporting Eminem in Auckland on Saturday night, were told on Thursday they would be refused entry into New Zealand.
They were also axed from the Big Day Out in Auckland in 2011 due to complaints about homophobic lyrics.
Band founder Tyler, the Creator took to Twitter on Thursday to vent his frustration about the New Zealand government's move.
"OF is banned from New Zealand, again. They said we were `terrorist threats and bad for the society' or whatever," he tweeted.
On Friday, fans confronted Mr Key at Wellington Airport to voice their disapproval of the decision.
"I don't know why the decision was made so late," he said.
"There'll be plenty of people who go to that concert who will be frustrated by that. I know because I ran into a few of them when I was coming off the plane arriving in Wellington."
Mr Key said he didn't know any of the details of Immigration New Zealand's decision to ban the group but he is sure they had their reasons.
When asked exactly what the annoyed fans said to Mr Key, he replied: "They said that they were frustrated that they won't be able to see them".
Anti-sexual violence organisation Stop Demand launched a last-minute bid to stop the group entering New Zealand, claiming their lyrics are hate speech and offensive toward women.
Band manager Christian Clancy said Odd Future weren't told about the ban until hours before their flights.
Odd Future was added to Saturday's Eminem bill last week at Western Springs after Grammy Award-nominated rapper Kendrick Lamar pulled out.
Tyler, the Creator has previously defended his work as no different to film directors portraying extreme violence such as Quentin Tarantino.
His albums have featured disclaimers and lyrics saying his work is fiction.
