The issue with the horse mogul and the trade minister is not whether the $150,000 donation to the National Party was legal - it was handled and disclosed entirely in accordance with current laws - but to what degree it shows our current legal framework governing donations is fit for
Matt Nippert: $150,000 donation - Money in politics and why it matters
We are not at the wildly distorted level of United States politics (where upwards of US$500 million is said to be required to mount a credible campaign for president) but our party system requires funding which - unless parliament comes to an unlikely agreement on state support for political parties - inevitably introduces the vexed issue of political fundraising.
The obvious risks of conflict - from parties receiving money from vested interests, then having to set laws and regulations governing such interests - are generally dealt with through transparency and disclosure.
As much as those on the left are critical of the potential influence of industry donors like the Talleys, or those on the right look askance at union money flowing into party coffers, the motives of these organisations are widely understood and their membership are obviously part of our political ecosystem.
Where matters become murky is the case of donations from offshore where the origin of funds, and associated interests, are less clear. These are not academic concerns. Spy boss Rebecca Kitteridge made a rare appearance in Parliament earlier this year to say the issue was high on her agenda, and: "I can say we have seen activities by state actors that concern us."
Our present regime has a number of contortions which should be addressed. Parliament was quite clear it had concerns in this area when deciding to ban donations from foreign nationals over $1500. But there are no limits on donations from companies or other corporate entities, even where their ownership or control rests offshore.
Given New Zealand regularly tops World Bank rankings in being the easiest place in the world to set up a company, it is not difficult to see how this mechanism could be potentially abused.
This is not a loophole - the law was intentionally written this way - but it is worth weighing whether we should really be treating this as a feature of our electoral finance system rather than a bug. Resolving the issue is not straightforward, requiring either a potentially blunt hard-and-fast rule or a complicated test of control or ultimate ownership, and will run into vested interests of its own.
The justice select committee is presently considering this very issue, but there will be the temptation - given the committee is dominated by National and Labour MPs - to do nothing in order to keep the taps flowing. Both parties count corporate entities as major donors: National has traditionally raked in corporate donations, while Labour receives funding from the union movement.
Let us hope here they are able to elevate the interests of our democracy above those of their own coffers.
