The Opportunity Party is vowing to "clean up politics" by regulating lobbying and reforming political donations.

It would look to cap political donations and establish an independent anti-corruption body to centralise and coordinate action against corruption.

The underlying principle of the policy was simple, she said.

"New Zealanders should be confident that political decisions are made in their interests, not because somebody has the biggest cheque book or the best access to a minister.

In order to regulate lobbying, the party would introduce a Political Influence and Lobbying Bill that would create a one-year cooling-off period, "closing the revolving door" between ministers, senior staff and officials, and lobbying roles.

It would also create a mandatory, public and searchable lobbying register, with quarterly disclosure of who lobbied which office-holders, as well as a statutory code of conduct for lobbyists and foreign lobbying safeguards.

The party's proposal would introduce a $30,000 cap per donor per party per electoral cycle, limit donations to registered voters, lower the public disclosure threshold to $1000 and apply advertising spending limits across the full three-year electoral cycle for parties and candidates.

The party would also establish an anti-corruption body with "investigative, prevention, and education functions, integrating and co-ordinating existing anti-corruption responsibilities".
