Kelli Pike
Trustee
Tena koe, No Maruawai ahau. Ko Mataura toku awa. Ko Hokonui toku maunga. Kei Kirikiriroa matou e noho ana inaianei. Ko Ngati Apa toku iwi. Ko Barnes raua ko Koroheke toku whanau. Ko Kelli Pike toku ingoa. I have worked with Go Eco since 2016, and during that time have deepened my understanding of the impact of consumerism, capitalism and colonisation on our environment, and how they impede climate action. I entered the environment sector after making a living from what others considered excess - by buying and selling second-hand items. It opened my eyes to the issues of waste and the change that is needed by consumers and manufacturers. I believe that real progress for climate justice comes from communities, who are appropriately resourced, and will always be an advocate for them.
Aroha Beckham
Trustee
Ko Kai Tahu rāua ko Ngā Puhi ngā iwi o tōku ūkaipō. Ko Tūwharetoa rāua ko Whanganui ngā iwi ō tōku matua. He tamaiti tēnei o tō tātou Awa Tupua, ko Whanganui tērā. I have an extremely diverse background and the one commonality in all the roles I have been involved in throughout my lifetime, lead back to the holistic wellness of individuals, whānau, hapū, iwi, and our environment – Te Tai Ao. Here in Whanganui we understand the health and well-being of our awa and the health and well-being of us as a people, go hand in hand. They are a direct reflection of each other, one cannot be without the other. Hence the whakatauki, “Ko au te awa, ko te awa ko au.” This whakataukī is part of the reason I chose at the start of this year to trial a ‘zero-trash’ lifestyle. It has been an interesting few months, not without challenge – and I believe being part of Para Kore can only enhance this way of life!
