Each team will have a minimum of four games with matches being played over 12 minutes each way. There is just three minutes between one match ending and the next starting and any team turning up late will find themselves being defaulted.
"You can't muck around, we have so many games to get through in one day that it's pretty much a case of go, go, go," Pawson said.
"It doesn't take long for teams to get the message, they soon understand the importance of keeping things moving."
Pawson's side will be one of the favourites for the 13th grade title after coming fourth on this season's Travel League competition, which had them competing against the best teams in their age group from the greater Wellington area.
But he is quick to say the standard of play in each of the grades is so high that nothing could be taken for granted.
"You can never guarantee anything. Looking at our grade there are probably four or five teams who could make it to the final," he said.
"Consistency is the thing, you need to play well in every game to be there at the finish."
No Wairarapa clubs were among the winners last year, when North Wellington won the 7th and 14th grades, Onslow the 10th and 11th grades, Upper Hutt the 8th grade, Petone the 9th grade, Miramar the 12th grade and Porirua the 13th grade.
