Finance Minister Grant Robertson's letter to Reserve Bank Governor Adrian Orr has been a highly effective piece of political theatre.
But if Robertson and his Government care as much about soaring house prices as the letter suggests, they need to act themselves.
Extending the bright-line treatment around the sale ofinvestment properties is the most obvious and easiest place for them to start.
In the face of mounting pressure on house prices, Robertson appeared to take a bold and controversial step in sending his letter calling for greater consideration of the issue in its monetary policy decisions.
But the RBNZ was already backing away from further interest rate cuts in the face of increasingly positive economic news - including the prospect of vaccines.
Economists have been quick to note that the letter is unlikely to make any material difference to OCR decision-making - although the market has viewed it as a nail in the coffin for further cuts.
Meanwhile the Reserve Bank has treated the letter as an invitation to get more actively involved in the broader house price debate, something that suits the current Governor's expansive world view to a T.
Orr and Robertson may be genuinely at odds here, but both are cut broadly from the same liberal-progressive political cloth.
Even more conveniently the rules were initially introduced by National and supported by Act.
Ironically, this latest move might have flown under the radar had Act not put out a press release claiming it was step towards a capital gains tax by stealth.
Extending bright-line rules would not be a silver bullet for house prices.
But it would be a step towards balancing tax treatment that this country needs to take if it is to begin the shift away from a property-obsessed investment culture.
Perhaps the PM was right; a true capital gains tax may have been a step too far for the majority of New Zealanders.
But for the majority of her Labour Party supporters it was a no-brainer.
It is that frustration from their own base that is creating the house price pressure for Labour.
