The debate’s tax promises stop at GST. Roads still have to be paid for

Christopher Luxon and Chris Hipkins agreed on one thing in Tuesday night’s TVNZ leaders’ debate. Neither will raise GST. Luxon added income tax to the list. “We’re not lifting GST, we’re not lifting income tax,” he said.

That is the promise most business owners will remember, and it covers the two taxes least likely to move anyway. 1News reported that both leaders stopped short of guaranteeing other existing taxes or charges would not rise. Fuel excise, road user charges and levies all sit in that gap. Those are the ones that show up on a freight invoice.

Fuel tax is where the two plans split

The sharpest tax exchange came when both leaders were asked to commit to no increase in any existing tax next term. Both said yes, RNZ reported. Hipkins then pointed at National’s planned fuel excise rises. “He’s putting up fuel tax by 25 cents a litre,” he said. Luxon later said he had misheard the question.

Labour’s answer is to freeze petrol taxes for a full term. With petrol at a record $3.52 a litre, that will appeal to anyone running a fleet. It also has a cost. Economist Brad Olsen told 1News that Labour’s fiscal plan leaves out the increases to fuel excise and road user charges, “and that does leave a pretty big hole in potentially the land transport fund”.

That fund pays for roads. If the excise does not go in, the money comes from borrowing, from other charges later, or from building less. A fuel tax freeze decides who pays for roads and when. Labour has not said who.

National has the argument but not the numbers

National’s line all night was that Labour cannot fund its promises. Campaign chair Simeon Brown put a number on it afterwards, claiming $18 billion in unfunded promises. Labour rejects that figure.

The trouble is that National has not published a fiscal plan of its own, and Hipkins used that on the night. “You would be able to make the same claim if you actually had a fiscal plan,” he told Luxon. Olsen made the same point with less heat. “It’s pretty hard for anyone to figure out where they’re going because we don’t have it.”

Labour’s plan is out, and The Spinoff reported it already contains a $90 million miscalculation. A plan with a visible error is still easier to budget around than one nobody has seen. Luxon told Newstalk ZB’s Mike Hosking on Monday that National’s would be out in the next couple of weeks, without naming a date.

What business heard

Olsen’s read on the business reaction was blunt. “Be it that LNG facility, be it the investment boost, there is a feeling, I think, amongst businesses watching the leaders’ debate last night that despite all of the talk of trying to be more bipartisan, there’s still a lot of potential flip-flopping.”

Luxon gave suppliers one firm answer. National’s plan to break up Foodstuffs will hinge on the Commerce Commission’s recommendation. “If they say no, we don’t do it.” On fuel he said the Government cannot control the pump price, which he blamed on “Donald Trump and this crazy war in Iran”.

Who won

Hipkins, narrowly. Of TVNZ’s panel of nearly 100 undecided voters, 49% said he had won their vote, 24% said Luxon had, and 27% were still undecided. 1News was clear that the panel is not a scientific poll. Newsroom judged that Hipkins “came out the winner, just”, and that Luxon did well on business and education.

The election is on 7 November. Before then, two documents matter more to a business owner than the debate result. One is National’s fiscal plan. The other is Labour’s explanation of how the transport fund gets filled once the fuel tax is frozen.
