For them, the saving grace is that the law seems unlikely to pass, given the current chaotic state of Australian politics.
The big power companies here have also dismissed it as irrelevant to the local market. Despite this, New Zealand politicians are being lobbied hard to consider very similar moves when they make decisions following the Electricity Price Review.
Some MPs are very receptive to the idea of a much tougher regulator here as well.
The angst comes as the Electricity Authority (EA) investigates complaints that generation-retailers are abusing their market power to push up wholesale spot prices.
In its latest update on the claim by a group of independent electricity retailers, the EA said it understood the investigation may "cause uncertainty" in the market and that it was considering ways to reduce this effect "as soon as practicable".
The claim of "an undesirable trading situation" (UTS) was received by the EA on November 8.
The joint claim by independent retailers Electric Kiwi, Flick Energy, Pulse Energy, Switch Utilities and Vector challenges the EA's explanation for a big spike in wholesale spot prices as being due to a combination of low hydro lake levels and a supply-limiting fault at the Pohokura gas field, the country's biggest.
The on-going Pohokura problem has caused generators to use more expensive forms of energy to generate electricity, which they say has forced up spot prices since September 15. The group wants the EA to reconsider its view.
