"There have been some shocking organisational lapses off the field," Dr Morgan said. "Quite frankly the competence level in the organisation of the sport is abysmal."
Dr Morgan wants New Zealand to change its style to "tap and go possession-based football". That would only be achieved if all teams from ASB Premiership level through to the All Whites began playing the same way.
"New Zealand does not know how to play football properly - that is pretty evident, I would have thought."
He said High Performance Sport NZ's funding system was flawed as it gave priority for funding for sports that were already successful instead of providing funding to help make sports become successful. Investment in football was important because of the sport's global importance and the potential positive spin-offs for the country.
"It's the biggest participation sport in the country, it's the biggest sport in the world. It has huge ramifications for us as a country if we can learn how to play it. We need a change."
