There are more than 300 schools competing nationally, including traditionally non-league institutions such as Auckland Grammar and Mt Albert Grammar.
The national secondary schools tournament is regarded as one of the best in the country.
New sponsors and partners have come on board and playing numbers have more than doubled since 2009.
While the Kiwis haven't beaten the Kangaroos since 2010, they have become consistently competitive and have honed their off-field dealings into a slick operation.
The Anzac test is set in stone, an annual New Zealand XIII match is in the pipeline and a high performance programme has been established.
"There was a lot of work to do but none of it would have been possible without the team here," says the modest Doyle. "Once we had the strategic plan in place, it was a matter of working towards all the benchmarks. I am happy to say we have achieved most of them."
Early on in the job, he met the Kiwis' management team ahead of the 2009 Four Nations tournament in the United Kingdom.
"I asked about our outcomes and goals for the trip, apart from winning games," remembers Doyle, "and there were a lot of blank faces. Obviously that had to change."
Now there are specific goals and outcomes around every Kiwis venture and analysis conducted before and after each trip.
Whenever the Kiwis come into camp, on and off-field expectations are set, with consequences if they are not met. It has led to a happier, more settled team and the players thrive in the more professional environment.
It was notable in Benji Marshall's post-match interview after the 2010 Four Nations triumph that he paid tribute to "Jim Doyle and the NZRL", an unusual occurrence in a unrehearsed final whistle interview.
