The damage Bridges suffered when the recording was heard came not because of the evidence provided of corrupt practice — on that issue it disappointed — but from what it told us about the kind of politics practised by the National leader.
The revelation that was most serious was surely the seeming willingness to offer for sale seats in Parliament to those willing to pay enough. This surprising and unedifying admission was compounded by the further comments he made about the ethnicity of those most likely to pay an inflated price for such a privilege.
At the centre of the claims and counter-claims is the vexed question of a large donation that was, as is admitted by all parties, made by a Chinese businessman to the National Party. No one is suggesting Zhang Yikun did anything wrong in making the donation, the dispute is whether the donation, once made, was handled in accordance with the law and was for a legitimate purpose.
It is worth pausing for a moment, however, to register the point that, sadly, it comes as no surprise that the donor at the heart of the dispute was Chinese. The reason for this is that in cultures less accustomed than our own to the rules as to how democratic politics should function, it is natural to assume that political support can be bought.
I recall that when I was an MP in the British city of Southampton, it was common for constituents from immigrant communities who sought my help and advice to approach me bearing gifts of various values. They saw nothing wrong about expressing their gratitude for services rendered or anticipated in this way. I would be obliged, as gently as I could, to decline to accept the proffered inducements.
It would clearly be a retrograde step and a blight on both our democratic system and our corruption-free reputation if such practices became endemic in our country. Donations on this scale, especially if concealed, can seriously distort our politics. The National Party was hugely advantaged by gaining such resources to spend on staff, organisation and advertising that were not available to their rivals.
The current saga is just one instance of the murky waters in which we could become swamped if the notion became established that the way to political influence lay through political donations.
The attitudes demonstrated by Simon Bridges have once again highlighted the risks we run as a result of our refusal to contemplate the public funding of political parties.
Whether we like it or not, those parties are an essential part of our democratic infrastructure; their proper functioning is central to any democratic system worth the name. Without the structure provided by the political parties, we would not be able to choose between one potential government and another and the whole point of democratic general elections would be lost.
The opposition to public funding seems to stem from the view that political parties are voluntary organisations which must be responsible for their own welfare and survival, and should not therefore look to the taxpayer for support. But this is unrealistic; their role as public institutions should not be obscured by the fiction that they are private associations.
As the current scandal demonstrates, that fiction places us all at risk. We cannot afford to tolerate a situation where private money buys influence in public affairs. A properly functioning democracy is the responsibility of all of us; some of us might give up our time and effort to ensure that the necessary infrastructure is in place, but others should, as taxpayers, be ready to make a similarly valuable financial contribution to that essential purpose.
