But a co-promoter for the event, Brent Eccles, was saddened that fans were focusing on the negative when the concert ended up being "incredible".
"For a band that went out of their way, cancelled shows, cancelled press, really did the hard yards to even play that event, for something like this to be said it is incredulous.
"I stand by the band 100 per cent. They gave it their all, went out of their way to come play these shows and I don't think they deserve this criticism at all."
Eccles said the band helped raise a lot of money for those involved in the Christchurch terror attack as they sold a lot of tickets.
"That's the most important thing and that's what we should be talking about, really," he said.
Eccles also defended the song Vibes, saying that the hit is about love and people shouldn't take the lyrics out of context.
After the event, fans on social media pointed out that the song was not appropriate for the event because of the lyrics.
However, some fans were over the moon about their performance, praising them especially for singing Don't Forget Your Roots.
