At least four out of every five dollars donated to the two big parties is given secretly, as transparency around their political funding dwindles.
More than $31 million has been donated to registered political parties in the past six years, most of that to National.
Smaller parties like the Greens publicly disclose who provided most of their funding, but the big parties are secretive. 83 per cent ($8.7m over six years) of the money donated to National is from anonymous donors, and 80 per cent ($2.8m) of that donated to Labour.
The worst offender is NZ First: Most years, it allows every single one of its donors to remain secret.
And these are not small donations, ordinary people giving $20 or $50 to support their party. In 2016, the National Party took in $819,000 in donations between $5000 and $15000, while Labour gained $348,000 in the same range. And all of these sizeable donations are completely secret. Which means that we have no way of checking whether donors are getting favours in return.
This isn't good enough. To protect ourselves against corruption we need real transparency in this area, which means a much lower disclosure threshold - something around $1000, or even lower. Individual MPs have to disclose any gift they receive above the value of $500, and their parties should be treated no differently.
