Is this the secret Freemasons handshake?
The moment was caught at the 150th anniversary celebration of the Freemasons' 1859 formation of the Canterbury district at Christ Church Cathedral on Saturday.
Four men were spotted giving unusual-looking handshakes, the right hand rolled slightly more to the left than usual.
District grand secretary Ron Sutherland said he shook "a lot of hands" during the weekend celebrations in Christchurch, but, "not every handshake I gave was a secret handshake".
He declined to describe the handshake because he had undertaken "obligations" when he joined.
However, "it's nothing that can't be found on Google".
More than 200 people from Britain, India, Singapore, Thailand, Malaysia and New Zealand attended the celebrations.
Sutherland said there was talk at the meetings of the new focus on Freemasonry brought about by American author Dan Brown.
"From what I understand, he was quite complimentary," he said. Sutherland said storytellers were naturally drawn to "an organisation that has got some mystique about it".
