Labour wins NZ election after backing from NZ First. Bankers' SA Galaxy: 31% Lib, 30% SA Best, 26% Labor

The New Zealand election was held on 23 September, with final results released on 7 October. The conservative National won 56 of the 120 seats, Labour 46, the anti-immigrant populist NZ First 9, the Greens 8 and the right-wing ACT 1. As a result, the right held 57 seats and the left 54, with NZ First's 9 seats required for a majority (61 seats) for either the left or right.

26 days after the election, and 12 days after final results were published, NZ First leader Winston Peters today announced that his party would form a coalition government with Labour. With NZ First backing, the left bloc has 63 seats, a clear majority in the NZ Parliament. This outcome ends National's nine successive years in power, in which Labour had utterly dismal results in the three elections from 2008-14.

While the time taken after the election to form a government may seem long, it is not by international standards. Following the Dutch election in March 2017, a coalition government was not formed for 208 days. The German election was held on 24 September, with final results known on 25 September, but government negotiations only began yesterday.

Bankers' SA Galaxy: 31% Liberal, 30% SA Best, 26% Labor

The Australian reported today that a SA Galaxy poll, conducted for the Australian Bankers Association 10-12 October from a sample of 806, gave the Liberals 31% of the primary vote, SA Best (Nick Xenophon's SA party) 30% and Labor 26%. The next SA election will be held in mid-March 2018.

This poll is not a media-commissioned poll. The ABA is an anti-Labor lobby group that wants to stop the proposed SA state bank tax. Polls such as these are prone to selective release; it is unlikely the ABA would have released a poll with Labor doing well.

The last media-commissioned SA Galaxy poll, in late June, had the Liberals leading Labor 34-28 on primary votes with SA Best on 21%, and a 50-50 tie between the major parties after preferences. If this ABA Galaxy poll is accurate, it implies that SA Best has surged 9 points since Xenophon announced his candidacy for the Liberal-held seat of Hartley.

In the better Premier question, Xenophon had 41%, with both incumbent Premier Jay Weatherill and opposition leader Steven Marshall at 21%.

If these primary votes were replicated at an election, SA Best would win many seats on Labor preferences, and could be the largest party in SA's lower house. Such an outcome would break the two party duopoly for the first time in an Australian Parliament since the early 20th century.

However, there are still five months to go before the election. Even if this poll is accurate, it could represent SA Best's high point. Both major parties will attack Xenophon during the election campaign, in an attempt to undermine his popularity. Labor will use Xenophon's controversial Senate decisions against him.

Although Labor is third in this poll, they are not out of the running. If Labor can take a few percent from SA Best, they would be more likely to benefit on preferences than the Liberals. If Labor retains office at the next election, it will be a fifth consecutive term for them.

After 14 years in office, Queensland Labor was demolished at the 2012 Queensland election, and NSW Labor had a similar fate after 16 years at the 2011 NSW election. A SA Labor victory after 16 years would be a remarkable achievement.
