Last year 5338 young players registered for club rugby in Northland, and this year it is set to reach close to 5800. As well, the number of senior players has risen from 1934 last year to 2009 this year.
Northland had the facilities to enable growth but Mr Shipton said it was as much about the organisers and coaches to keep kids and families involved.
The Kamo Rugby Club's Gordon Ball has been part of the club for 20 years, and said the key to keeping kids on the field was organisation.
"People are just so busy these days ... so you've just got to be organised, and stay on top of things.
"Kamo already has a great network of support, with families involved that have a long history with the club, they're the ones that keep the ball rolling," Mr Ball said.
While Kensington Park was the base for Saturday junior rugby, Mr Shipton said it was at maximum capacity with games there, so under-14s, 15s and 16s had to play out at the clubs.
With so many competing demands for Kensington Park, the Whangarei District Council has decided to review the park's management plan.
