Problems in the two main governing partners to the National Party of New Zealand PM John Key.
The right-wing ACT party has had a leadership change. The new leader is the former National Party leader, Don Brash.
The Maori Party is unhappy about the shift in ACT (largely because when Brash headed the Nats, the latter party wanted to abolish the separate Maori constituencies. Meanwhile, the Maori Party has suffered a split, and may face competition in Maori electorates.
New Zealand has a general election, as well as a referendum on the electoral system, ((Which will not, however, affect the Maori seats directly.)) on 26 November.
