Prime Minister John Key allegedly pulled the pony-tails of two school girls while on a visit to the national museum.
Mark Blackham of BlacklandPR said his 12-year-old daughter watched last night's television news and said, "that's what the Prime Minister did at Te Papa to my two friends".
Mr Blackham, who has advised senior politicians from Labour, National and the Greens and the Internet Party, said his daughter had visited Te Papa on a school trip late last year.
He has since blogged about the incident on his political strategy blog, Political Business.
"I guess she was a bit amazed, she was just intrigued that it had happened to her friends as well, she was surprised," Mr Blackham told the Herald.
