How are MP's currently and/or going to look after New Zealand's interests?
Over New Zealand law is Trade agreement and/or other international agreements. So a MP's can not make New Zealand laws for New Zealand interests unless we do not have such agreement taking away local New Zealand laws. Otherwise New Zealand will need to remove such agreements in order for the Parliament in New Zealand to be Sovereign.

Will the USA trump other countries interests? Wall Street, private banks creating money and no action on climate change?

The elections office only allows phone number of those standing in the Mount Albert By-election to be release to the media in the event media request such information. Yet on the elections websites are contact details of some Parties. Peter Wakeman views it unfair for his facebook e-mail not to be release given local elections give such information to the public.
