Denise first started volunteering and working casually for Paper4trees in 2018 before taking a break to have her son. She is excited to have been able to re-join the team in 2020.
Denise grew up in Germany and moved to New Zealand in 2008. While still having much to learn, Denise continues to take an interest in Māoritanga, the land, and the people of NZ. Denise is a former early childhood teacher whose interest in sustainability was sparked at university and with the help of some passionate teaching colleagues. She therefore very much enjoys the dialogue with schools and early childhood services at Paper4trees alongside supporting the team with administrative tasks.
