Who are the New Zealand parties standing in the election? What are their policies?

The Elections site has a list of all parties registered to stand in the 2011 election, including links to the party's official sites.

Note: One party don't have an official site linked from here. You will need to do a google search, searching for the party name as phrase: When searching google, if you put double speech marks " " around your search term, google will search for it as a phrase.  Very handy if you're looking for something in particular and you know the words will be in that order. For example: "New Zealand Pacific Party". You may not find their official site, but you will find information about them.
