Just as a suggestion; because its interesting stuff. Maybe have a read of some of the work the Waitangi Tribunal has produced over the years.
What's been happening in recent years is Act, Don Brash and others approaching the issue with race baiting sound bites. Its mostly vibes and bad faith.
Compare it to the huge amount of research and historical context the Tribunal has put into their work.

In any case, to understand where Maori are coming from, its important to remember this finding: "... rangatira who signed te Tiriti o Waitangi in February 1840 did not cede sovereignty to the British Crown.
Ie, if sovereignty wasn't ceded back in 1840 why should any Maori give two hoots what Seymour thinks?
