The prime minister has poured cold water on the prospect of government support to save Moana Pasifika, after confirmation the Super Rugby franchise will not be involved in next year's competition.

New Zealand Rugby has ruled that the $12m plan lacked the financial security it needed.

Moana Pasifika will not play Super Rugby in 2027 after a last-minute bid to rescue the financially troubled franchise failed, New Zealand Rugby said on Wednesday.
