I contacted National, Labour, Act, The Maori Party, NZ First, the Greens, the Opportunities Party, the Conservatives and United Future to ask them all three questions. Five parties responded to my questions and I published their responses in full and un-edited. My attempts to get a response from the Maori Party were unsuccessful so I read the 2014 Policy Manifesto on their website to try to find the answers to the questions I had asked both them and the other parties.
I was shocked to discover that their latest manifesto dated 2014 contained no Immigration policy at all.
The Maori party had answered my questions previously about Israel so I was surprised when they did not reply. Now I am wondering if it was because they do not have an immigration policy.
