When I read last week that Tony Blair had published a 5,600-word essay on everything that ails Britain, every instinct told me not to read it. But I could not help myself and read it anyway. Read more
This week’s Budget confirmed what most New Zealanders already suspected. The government’s finances are tight, the deficit persists, and there is no pot of money waiting to be spent on the country’s problems. Just as well, because government spending never delivers growth or prosperity. Read more
In this episode, Oliver talks with Eric about Budget 2026, which brings the forecast surplus forward a year but rests on a series of lucky breaks, from oil prices falling to fiscal discipline surviving the election and coalition negotiations. They weigh what is driving spending well above 2019 levels, the case for superannuation reform, council incentives to go for growth, the shrinking public service, and why Treasury's tobacco and alcohol excise forecasts keep going wrong.

By 1974, at the Allensbach Institute she had founded a quarter-century earlier, Elisabeth Noelle-Neumann had given a name to a puzzle first visible in her election research of the 1960s. West Germans would tell her pollsters one thing in private; in public they would say something else, or nothing at all. Read more
In this episode, Oliver talks with senior fellow John Howard about mounting geopolitical instability, from Iran and the Strait of Hormuz to Trump's visit to Beijing and the growing pressure on Taiwan. They discuss what these crises mean for New Zealand's energy security, political leadership, European security, business risk, and the need for more serious strategic thinking. Read more
Observers of European politics know Germany’s Alternative for Germany (AfD) as a right-wing, populist party, probably extreme, certainly friendly to Russia. Less visible from the outside is that the AfD is not an ordinary opposition party that might win an election, govern badly and then be voted out. Read more
When Jim Chalmers stood up on budget night and announced the end of negative gearing on established properties, he assured Australians it was worth breaking a promise for “right and justifiable reasons.” Grant Robertson, New Zealand’s finance minister, said something remarkably similar in March 2021 when he broke his own promise not to extend the bright-line test on property. Robertson called his earlier commitment “too definitive.” A New Zealand Herald columnist observed that this sounded a lot like “too honest.” New Zealanders know how this story ends. Read more
In this episode, Oliver talks with Roger Partridge about the Government’s decision to legislate to stop the Smith v Fonterra climate change case. They discuss why Parliament was right to step in after the Supreme Court reinstated a claim the Court of Appeal had unanimously struck out, the causation problems at the heart of the case, and why media claims of an attack on judicial independence get New Zealand’s constitutional order backwards.
