Pita Sharples has announced that he wll oppose Wayne Mapp's Employment Relations (Probationary Employment) Amendment Bill. The bill won its first reading 63 - 58. Sharples' about-face will cut that majority, but not by enough for the bill to fail; for that to happen the rest of his Maori Party colleagues (or New Zealand First) would have to vote against it as well.
Sharples changed his mind because of pressure from the flax-roots within his electorate. Which shows us the way forward on this: if you are on the Maori Roll in Te Tai Hauauru or Waiariki and you oppose the bill, either write to your MP at Parliament (the postage is free), or better yet, schedule an appointment at their electorate office. The Maori Party's MPs will at least listen to their constituents, and if people speak up, they can hopefully be flipped one by one so that Mapp's bill will fail.
