Norman said on TVNZ's Q&A Show that the Reserve Bank should print more money to take pressure off the high New Zealand dollar.
But Norman's suggestion has been met with scorn by National Party politicians and economists, and by some commentators.
"The latest idea of the Greens to print money, that's a pretty wacky idea. If printing money made you rich, Zimbabwe would be the richest country on the planet and it's not", Prime Minister John Key told TVNZ's Breakfast programme.
And Kiwiblog's David Farrar wrote: "There are basically two sorts of countries that print money. Those that are bankrupt, and those whose economies are so stalled that the central bank cash rate is as low as it can go."
The idea of printing money is not new. However, New Zealand has long relied on the Money Fairy to supply freshly minted money to the Reserve Bank.
Nobody knows where the Money Fairy comes from, or why she delivers bags of cash at opportune times. Her mysterious deliveries usually occur a short time after Reserve Bank officials have noted the need for more cash.
The Government appears to be happy with the current arrangement, whereby rather than printing money the Reserve Bank awaits its magical deliveries of cash.
The design and production of bank notes would be time-consuming and costly, and would probably involve the contracting out of the production of special polymer notes to a specialist mint, such as Note Print Australia Limited.
It is easier to simply wait for a magic fairy to just drop cash into the Reserve Bank's vaults.
But it remains uncertain what the Government's reaction will be if the Money Fairy ceases to deliver those bundles of cash, since printing money is clearly something no sensible government ever does.
