Winston Peters is threatening to refuse interviews with RNZ, unless it apologises over its reporting on his Party.

The Court of Appeal has dismissed a Serious Fraud Office bid to overturn a court ruling two men were NOT guilty of obtaining hundreds of thousands of dollars by deception for the New Zealand First Foundation.

The money wasn't deemed a 'donation', because the funds weren't deposited into the Party's account.

Party leader Peters claims the media ran 'attacks' on NZ First, and says RNZ won't get away with it.

"You'll see what I do- because if they think that they are not going to be held accountable, they couldn't be more wrong."
