Event local organising partner, HTV spokeswoman Diane Lee, confirmed that JK Entertainment did not want fans to perform the haka but did not say why B.A.P. has three No. 1s on Billboard's World Albums chart and an international fan club, including in New Zealand, where members are called "Babyz".
Paul Moon, Professor of History at AUT University's Faculty of Maori and Indigenous Development, disagreed that the haka was a health and safety hazard.
"Unless someone fell, or bumped someone else, then I can't see how it would be a specific health and safety concern," said Dr Moon.
He said the role of haka has changed over the last few centuries, even within Maori communities.
"What we are seeing now is an acceleration in that rate of change, much of which is brought about by a combination of the impact of social media and New Zealand being one of the world's most ethnically diverse societies," Dr Moon said.
Korean pop music was leading a resurgence of Hallyu, or the Korean Wave, according to a report released by Victoria University this week."
Neo-Hallyu, led by K-Pop, has an expanded fan base, including teens and those in their twenties, a demographic group familiar with the digital environment," said the authors of "Korean Wave: A Sourcebook".
"The new Korean Wave is spreading through social media beyond Asia to every corner of the world, including the US, Europe and South America."
Associate Professor Stephen Epstein, one of the editors of the book, estimated the number of K-Pop fans in New Zealand to be around 6000.
