THE Naitasiri Northern Bulls Rugby Union started its pre-season club competition last week.
Already 26 teams have shown interest in registering for the union.
However, union officials say only 24 clubs will compete in this season's weekly competition which starts at the Naluwai grounds on Saturday.
"We're urging clubs to pay their registration fees in full now because we will only be registering 24 teams for our clubs," said union secretary Jone Kaisuva.
The Northern Bulls RU competes in the Fiji Rugby Union B division competition.
Last year the union made its return after a lapse of several years.
Kaisuva said they had received many responses from clubs.
The union had 18 clubs affiliated under its umbrella last year. Northern Bulls narrowly missed out on a B division semi-final spot last season.
"Many teams have shown interest in joining our competition but we will go with the first 24 teams.
"We will take it slowly as our main goal is to improve our performance in the B division this season."
