The announcement about reduced coverage comes as the provincial unions and NZR head office face off over future governance of the sport on these shores.
The proposed changes to the provincial game would also see responsibility for player development moved to Super Rugby franchises.
A structured formalised competition involving all New Zealand provincial teams was launched in 1976, with sides playing for promotion and relegation between divisions. Until the introduction of professional rugby with the Super 12 in 1996, the NPC was the highest form of the domestic game in New Zealand.
The competition has faced a series of restructurings since 2006.
Since its inception, Auckland has won the most titles (17), followed by Canterbury (15) and Wellington (5).
Taranaki won their second title in 2023, beating Ranfurly Shield-holders Hawke’s Bay 22-19 at Yarrow Stadium.
