She said they put up a fence around their lawns at the Government Gardens this week.
"It has been all go setting up," Dyson said. The temporary fence would also act as protection for spectators and other players, so they did not get hit by the croquet balls.
All five lawns - which will be in action for the next seven days - have been separated by a thick pipe.
"We also have two temporary sheds, one we are using for an admin building and the other one is for visitors to put their things in."
Dyson explained the croquet hoops, which the balls pass through, were very skinny for the world championships. She said they were only the width of a croquet ball and the side of a bank card.
"That gives you an idea of the quality of the players and the accuracy needed."
Golf croquet is different to association croquet, which is the other main discipline of the game. Golf croquet was a lot quicker.
"It is interesting because association croquet is the purist form of the game and golf croquet has come in during the past few years, about 10 years ago I think, and has been very popular," she said.
"Golf croquet is a lot quicker and it is not as technical - it is a little bit like test cricket versus one-day cricket."
There are no Rotorua players in the world championships.
