Twyford's accusation arises from a comment posted by Collins referencing an Instagram post, in which the Ross makes the statement "204 countries + 7 seas and I had the privilege of meeting you".
Collins' follow-on Tweet suggests she took this post to mean the pair had travelled to 204 different countries.
The post, in fact, references a popular romantic meme, which alludes to the serendipity of the couple meeting.
Twitter semantics aside, the discussion between the pair of politicians raises an important debate about what the Kiwibuild initiative should achieve and who should benefit from it.
Twyford leapt to KiwiBuild's defence, saying a generation of young Kiwis with "good jobs" are being priced out of the housing market, which shows just how bad the situation has become.
Twyford has previously said KiwiBuild is "middle class" and "aspirational" and today he went further, saying it's really about increasing homeownership levels.
Collins said today: "Hats off to the young couple but to say they're a family in need is entirely wrong. Phil Twyford has been saying KiwiBuild is for low-income people with children but on the weekend, a home went to a very high-income couple."
Instead of KiwiBuild, National would reform the Resource Management Act "which has stopped development and we would reform planning laws for the building and construction sector and actually get the market to build houses", Collins said.
