The National Party is being criticised for having an upside-down Tino Rangatiratanga flag in the background during leader Todd Muller's speech in Te Puna yesterday.
But Tommy Wilson, Te Tuinga Whanau Support Services Trust executive director, said it was "totally unfair" to pin the mistake on Muller who had just hired the Te Puna Rugby Football clubrooms hall for the event.
The mistake led to dozens of tweets to the National Party and jokes about what the upside flag meant.
Wilson, who is also a club member, said the forum was attended by at least 300 people, including tangata whenua, Maori Party and Labour Party supporters.
"I think it is a very cheap shot to blame Todd as the flag has been hanging that way for at least a year and no one has said anything until now. Even I didn't notice it was the wrong way up and I have been in that hall many times," he said.
