What started as a desire to save one river in the Canterbury foothills has become a life-time commitment to politics and improving the outcomes for all communities.
Being profoundly deaf makes everyday life more challenging. But Mojo's journey proves that with support and commitment, disabilities need not stand in the way of making the most of every opportunity.
Mojo first became actively involved in politics while running a forest consultancy business in Colgate, south of Christchurch. She became a founding member of the Dam Action Group and led the charge on the successful campaign opposing the Central Plains Water scheme.
She soon realised that she needed to move beyond the local. Inspired by former neighbour Rod Donald (previous Co-leader of the Green Party) she took the plunge. "I just wanted to speak out in defence of our water and our environment and be heard."
She was the Green Party Strategic Policy Advisor for five years before being elected to parliament in 2011 - New Zealand's first deaf MP. Her election was inspiring to the disabilities community internationally, and she was humbled by the support she received from all corners.
Mojo's first political battle was to get the tools she needed to do her job, such as electronic note takers. The episode was a typical example of the discrimination that people with disabilities experience in the workplace, but eventually Mojo won - her first of many parliamentary victories.
She champions disability issues in the House, and her Action For Animals campaign has gone a long way towards ensuring that animals are protected from cosmetic and psychoactive substances testing.
The Greens have got our Mojo working harder than ever.
