A Massey University researcher is adamant he's not studying surf rage as an excuse to hit the water and says the aggressive behaviour is common on New Zealand water.
Jahn Gavala said surf rage, which occurred when surfers got protective of their local surf and could lead to intimidation and even physical assault, was prevalent especially in places where there were big surf breaks and was often visible to other surfers as it often stemmed from people protecting their space or surf break.
"People have ownership or de mark certain spaces in the surf zones, they form packs of surfers, they use verbal intimidation, physical intimidation and the raging is being physically beaten up - boards broken, cars broken."
The 42-year-old, who has just returned from two-years leave to surf in Indonesia, will be the first psychologist in New Zealand to look into surf rage and the research will make up part of his PhD in Psychology.
"There's an idea of surfers being really mellow and relaxed basically and in fact some surfers are pretty amped and not that chilled out."
