3.  What is the percentage of votes required? For example if there are 1000 people on register, how many need to vote?

Trust Board Reply:

The Iwi should decide these matters, by proposing ideas at the Consultation Hui, which can be ratified in a vote taken by all registrants prior to the Deed of Settlement. Issues to be considered include:

Whether the ‘majority’ includes all those who are registered, or only those who vote
Simple Majority:         51%
Significant Majority    75%
