A lobby group says organisations wanting to promote their policies in this year's election are being gagged by the Electoral Finance Act.
The Freedom of Speech Trust is campaigning for the repeal of the Act, after being set up last year to try to stop it becoming law.
A trustee, John Boscawen, says while his organisation is not affected by the Act he knows of four organisations that are.
He says one, Family First, has prepared a brochure but to distribute it nationwide would cost $140,000, more than the amount a third party is allowed to spend.
He says that the Act prevents third parties from spending more than $120,000.
Mr Boscawen says he would like to see the Act repealed before this year's election.
