John's political outlook emerged in his younger days on the jazz circuit, when he played in the Rodger Fox Big Band and put out two albums with the band Strange Fruit. The beaten-up baby grand piano in the corner of the room looks like it's had plenty of tunes thrashed out of it. But his music has been recently eclipsed by a new passion - electronic cigarettes. He's been puffing on one throughout the conversation.
He said he'd tried everything: patches, lozenges, cutting back, cold turkey. At age 59, John was introduced to Smoke Stiks, an American brand available on the internet.
"I've got something to hang on to. I've got something to puff on," he said. "That's what most of the smoking habit is, having that nicotine hit the back of your throat."
Like his Parnell counterpart, he threw himself into a new career - marketing and selling the electronic cigarettes with little red LEDs on the end.
Despite the hype, the product falls into a legal grey area: The Ministry of Health says it can be sold in pharmacies "as a gadget which consumers may choose to use as a social prop or as an item which is to be used interchangeably with cigarettes".
As long as it is not marketed as "a way to give up smoking" it can sidestep the lengthy MedSafe approval process. Individuals can also buy it over the internet, as John does.
A starter kit costs $130 and a five-pack of nicotine cartridges - enough to last at least a month - is about $30.
Funnily enough, the other John's economic management is working in his favour right now. "With the dollar the way it is, the price is coming down. It's great."
