Like it or not - and National certainly will not like it - the Waitangi Tribunal has potentially thrown a further spanner into the Government's privatisation agenda.
John Key, however, really has little choice but to accept what is effectively a request from the tribunal to hold off floating shares in Mighty River Power until the tribunal has made its full ruling on what rights and interests in water are guaranteed to Maori under the Treaty.
The tribunal now says its report will be ready in September. It is not saying when in September. Realistically, the Government probably did not expect it to be finished any earlier.
Though reluctantly, the Government will thus be prepared to wait until then. Not to do so would look churlish, petty and overbearing. It would mean more friction with the Maori Party. It would run counter to National's tactic of downplaying any sense of concern about the question of water rights frustrating its privatisation plans.
There is also a view around Parliament that the more difficult Maori and the tribunal make things for the Government, the more National benefits in terms of support from the wider Pakeha electorate.
