Coaches were trained in injury prevention, he said.
"At secondary school through to seniors, it is a compulsory annual Rugby Smart course they must attend before coaching. It is a coaching and development programme aimed at injury prevention. We know our coaches are armed with valuable information to pass on around injury prevention and techniques to make the game safer."
Local clubs are hoping the FIFA World Cup generates a spike in player numbers.
Although more younger players turn to football than rugby, the beautiful game has about 115,000 registered players nationwide across all age groups, compared with rugby with more than 148,000.
FIFA has designed a football injury prevention programme called FIFA 11+, which has been rolled out in conjunction with New Zealand Football.
The extensive warm-up programme aims to reduce injuries in players aged 14 years and over, although it is up to individual clubs to take it on board.
Waikato Bay of Plenty football development officer for Western Bay Peter Smith said injuries had never been a huge issue, and the federation had been pushing the FIFA 11+ programme to minimise potential injury risks.
Events such as the World Cup and next year's Under 20 World Cup, which New Zealand is hosting, helped to boost the game's profile and increase player numbers.
WaiBOP football chief executive said he could not comment on the increase in claims as he had not had a chance to study the report.
Physiotherapist Hamish Aston said the main injuries he dealt with were ankle injuries from tackling, hamstring strains from running, and the occasional knee injury.
Early in the season it was more common to see shin splint injuries from running on hard ground.
He was seeing more elite junior players in the 12-16-year-old age group who were "over-worked and over-trained".
