Our Whānau

Committee of Management

Ko wai au?

Pirihira was appointed onto the Mangatawa Pāpāmoa Blocks Incorporation in 2022. She served as Deputy Chair from 2023 and became Chairperson in 2025. She brings over 30 years of senior management experience in the private sector and more than a decade of governance leadership.

Born and raised in Tauranga Moana, Pirihira is proud of her Ngā Pōtiki whakapapa. Blessed with a tūpuna name, one handed down from her beloved nana, Phyllis (Pirihira) Haua — a woman of quiet strength and deep manaaki. While not known for being quiet herself, Pirihira honours her nana’s legacy with aroha and purpose. Her leadership style is more like her grandad Ray, who instilled in her the importance of accountability, integrity, and strong sense of justice.

She is the founder and Managing Director of Platform Agency and Tohu Studio, businesses she established in 2013. A highly strategic advisor, she is trusted by iwi, Māori entities, and private sector organisations to align vision, values, and long-term economic outcomes.

Pirihira also serves as a Director for Mangatawa Developments, Pacific Coast, and Pacific Lakes Retirement Villages, and as a trustee of Manawa Community Housing Trust and Ngā Pōtiki ā Tamapahore Trust.

A proud māmā to her 15-year-old son Nate, she comes from a family of five, the four girls, are well known for their loud laughter, passionate straight talk, and deep whānau bonds.

Ko wai au?

Kate brings a wealth of international experience to the MPBI table, grounded firmly in her identity as a Māori woman from Aotearoa. With over 25 years working in global sustainability, she has supported island communities across the Pacific, Caribbean and beyond to navigate the challenges of climate change and biodiversity loss.

As Executive Director of the Global Island Partnership (GLISPA) and Co-Chair of the Local2030 Islands Network, Kate is a connector – building partnerships that create lasting, real-world impact. Her approach is rooted in collective responsibility, kaitiakitanga, and collaboration – values that closely align with the kaupapa of Mangatawa.

Alongside her international mahi, Kate remains deeply involved in her own community. She serves as Treasurer of her marae, is a member of Te Takutai Moana Koea ki Tauranga and is active in whānau life. Her ability to bridge global and local perspectives is one of her greatest strengths and a valuable asset to the direction of MPBI. We’re proud to have Kate on our Committee of Management – helping guide our whenua into the future while staying firmly grounded in our whakapapa.
