The New Zealand Rugby League is taking on board recommendations that could bring radical changes to the sport.
It voted on Saturday to accept the governance plan proposed by SPARC with members overwhelmingly supporting game-wide constitutional reforms.
At a special meeting in Auckland, NZRL members fully endorsed findings and recommendations by the Independent Review Committee released last month.
SPARC chief executive Peter Miskimmin says the NZRL and its members have acted in the best interests of the sport to help rugby league grow and prosper.
He said the vote was almost unanimous in favour of change.
As a result of adopting the new constitution, the existing board will continue to hold office until it is dissolved in late May for the election of a new board.
Saturday's meeting also confirmed the two rugby league representatives on a four-man appointment committee, Peter Kerridge of West Coast and Cameron McGregor of Auckland join SPARC's appointees Sir John Wells and Sir John Anderson.
