Trudy Sandle, a goal scorer in Northland FC's promotion-clinching win over Rotorua United, led the way with 43 goals.
Walker said it was hard to understate how well Kamo had done this season.
"This was a massive achievement for the club to win three leagues is a fantastic effort but for all three to win the leagues without losing a game is almost unheard off," he said.
"This was by far the most successful year Kamo has had as a club."
"Individually we have had successful teams in the past but as a whole for three senior teams to achieve what they have this season is excellent, the challenge now is to build on this success going forward as the other clubs will want to put a stop to our success. "
Walker said his reserve team had a fantastic year, which supplemented the efforts of the two premier sides.
"The men's reserve team had a great year last year winning the league and the Stafford choat and to repeat the success this year is exceptional the NFF Fed One Reserve cup win was truly special as they were seen as huge underdogs," he said.
"The men's premier team after a couple of lean years came back with a bang this year and took out the double."
"The club has invested over the last few years with junior co-ordinators in place and we believe this is finally showing prominence in the results on the pitch."
