Below the top trio are another group who Cameron says "are heading in the right direction". They include Campbell-Kirk Waugh, who Cameron says has excellent management skills, John Rowbury, German-born Mirko Benischke, Isaac Terris and Mark Hester.
Referees have recently been criticised for the number of cards dished out and their lack of management skills - something Cameron, Gary Fleet, Bruce Grimshaw and Brian Precious, among others, prided themselves on.
"To have good referees you have to have good football," said Cameron, who these days, despite battling health problems, keeps himself involved as a coach of the referees on the panel.
Top referees are certainly not in it for the money. Referees in the Northern League are still paid $35 a match - unchanged in years - and $125 (up from $85) for ASB Premiership matches.
Many of the referees from the early days of the old National League (1970-80) are being sought for a reunion next year. Organiser Alan Boniface (aljoy@paradise.net.nz) is attempting to contact as many referees for the occasion which is likely to be early in the 2013 season.
