Saw this in today's NZ Herald:
Kokako Organic Coffee Roasters are turning 15 and to celebrate, they're having a knees-up at the roastery. Pop in for a free cuppa joe, snacks and a look behind the scenes at Kokako Roastery, 606 Great North Road, Grey Lynn, on Friday between 8am and 1pm.
A bit about the event on their site and an article in BeanScene stating:
Customers are invited to “drop by” and sample Kokako’s signature brews, enjoy a bite to eat, and go behind-the-scenes in the roastery to learn Kokako’s roasting secrets to 15 years of success.
