Using their own money, each volunteer will buy a fair-trade coffee for the first person that comes in after them.
"I think of the opportunity to make some sort of difference, even if it just affects one other person," says volunteer Robyn Bradley.
Kiwis' altruistic tendencies will be tested to see how long the chain goes for. Last year the chain went for over 200 people in one cafe says Wylie.
Getting the "buzz" will not only come from the caffeine hit but by the campaign's drive to "pay it forward".
"The barista will say if you opt for fair-trade, the coffee has already been bought for you as a gift, take this gift and pay it forward again. In the process of doing that the barista will also provide information about fair-trade to the person coming into the café," says Shruthi Vijayakumar, P3 Foundation's CEO.
Here, the undercurrent of hear no evil; see no evil will be blown out of the water as each café provides information on fair-trade; allowing customers to pay heed to the idea of "conscious consumption."
"Trade injustice is a big issue with developing country farmers often being ripped off," says Angus Coull, Marketing and Communications Officer of Fairtrade Australia New Zealand.
At its core, fair-trade supports and empowers farmers in developing countries to trade their way out of poverty he says.
Mt Albert's Cosset Cafe will be participating in this year's campaign. Co-owner Kellie Gray says she has noticed a change in the way people approach the food they consume.
"I think people are becoming more aware in wanting to know where their food is coming from, how people are treated and who are producing their food. It perhaps produces a happier coffee drinker," she says.
The growing support for ethical consumption has seen increasing numbers of cafes adopting the fair-trade principle.
"This is such an easy way to make a difference; it just means that you walk a little bit further to a fair-trade cafe rather than going to a different one," says Wylie.
The effort in seeing the "farmers behind the labels" means people carry the possibility of change in their pockets.
She hopes the next time you grab that cup of joe, you may spare a thought to farmer Joe, whose fair-trade coffee has just hit you with a wake up call.
