Each significant paper must be accompanied by a Regulatory Impact Statement, which lays out in detail the impact of a decision on the relevant stakeholders. This was an innovation of the Key government, and its power is that it is written by officials rather than ministers, so it is where you look if you want to find a fish hook glossed over in the main Cabinet paper.
The Regulatory Impact Statement on this proposal was clear in its impact and the risks.
Both Treasury and the Prime Minister's Office prepare short cheat sheets for their ministers highlighting the key elements of every Cabinet paper. An hour before Cabinet on Monday morning, senior Treasury officials sit down with the Finance Minister and his associates (including in this case David Parker) and discussed the key papers of interest at that day's Cabinet. At a similar time two floors higher, the Prime Minister's Office is taking their boss through a similar preview of the papers.
Unless all the officials involved were incompetent, which is highly unlikely, and the Prime Minister and Finance Minister can't read, also unlikely, there is no way they didn't understand that the Inland Revenue were lodging a bill to increase the tax take by $200 million and reduce people's KiwiSaver balances accordingly.
As an added protection Cabinet also has senior ministers who act as sweepers. They are normally alert for things that might carry ramifications others haven't thought of that either worry their constituency or affect the Government's broader standing. They serve an important alarm-raising function for the wider Cabinet.
Once the Cabinet decision is made, there are more protections around how the decision is announced. Ministers don't just dash off press releases themselves for significant economic matters. Any draft announcement involving government finances is shared with the Finance Minister's Office, and anything political with the ninth floor. It beggars belief that none of the public relations experts in those offices raised concerns with their ministers that the draft contained nothing about the GST hike for KiwiSaver.
So unless there is a total breakdown of the normal decision-making processes within government, which is highly unlikely, this decision and the underhand way it was announced was premeditated.
How on earth could you get to such a tone deaf point? After all, this is not a new government, it has been in office for five years. Ministers surely knew this decision would wind up ordinary New Zealanders and cement the perception they are a high tax, high spending government. They must also have known that trying to avoid actually announcing the change could be political suicide, particularly given the media had given them fair warning they were interested in this upcoming decision.
One popular explanation for this state of affairs is the Government has given up and have stopped caring what people think. This theory goes that they know they are on their way out and have stopped trying to politically manage things, content to shovel decisions through and get as much as possible done before they are turfed out. Weak governments can get to that point, but I don't think we are quite there yet, and no government would damn the torpedoes for the sake of $200 million and the tidy minds at the IRD.
A second one could be political arrogance. There is every sign the Government believes its own BS to an unwarranted degree, so maybe it thought it could spin its way through this issue in the same way as it has so many others. The Prime Minister is certainly adept at arguing black is white and that failure to deliver is the result of aspiration, so there's plenty of evidence for this theory.
An even more likely possibility is that ministers are getting completely out of touch with the public they serve. There is a very long series of announcements suggesting that is the case. The TVNZ-RNZ merger, the bike bridge, Three Waters, Trevor Mallard's appointment to Ireland and his pending knighthood, the bank credit changes, immigration policy, and industry pay bargaining are some that leap to mind. They are either completely inexplicable (think GST on KiwiSaver), or clearly designed to serve a part of Labour's power base to the bemusement or downright hostility of the general public. If you make enough unpopular decisions you can kid yourself that any negative feedback is par for the course.
Whatever the final cause of the Government's awry political antennae, it appears very likely the die has been cast and the public have made up their minds about this lot, and ministers increasingly know it.
For the evidence of that, see Grant Robertson's regular personal attacks on Opposition leader Christopher Luxon. It is likely Robertson realises the public's perception of his government as out of touch and ineffective is now baked in, and the only chance they have of surviving next year is to make the alternative government look as shop-worn as their crowd.
Expect to see much more attacking of the opposition over the next 12 months. Labour's strategists may not have been able to work out that adding GST to KiwiSaver this way was political poison, but they are aware that the only way to level the playing field for the next election is to drag the alternative government down and create as much doubt about them as there is about Labour. It's the 2005 and 2008 playbook all over again. And it won't be pretty.
