Strange experience, try not to stick around for too long.
Pros
Most team members are nice enough well meaning people.
Cons
Organisation operates on the belief of helping the environment when really are just pushing hard sales with counter-intuitive strategies and rules. Selling the idea of saving the planet more than actually doing anything productive/proactive/practical to enact real change. Hours are terrible. So many British transplants bringing UK office culture into the work environment, difficult to be passionate about making our country a greener place when Englishmen are butchering Maori names of places and providing oversimplified and often misguided explanations/understandings of local politics and culture. It's hard to work at Greenpeace and feel that you're doing right, when you actually care a lot about these issues and the organisation is willing to take advantage of your concerns to further take advantage of people.
