Doing the groundwork for future generations

We work in partnership for the future of our land. We recognise the mana of the ground we work on, and strive to respect people and place in all we do.

Nō reira, tēnā koutou katoa
Thus, our acknowledgement to you all



We work in environments where people have been living for hundreds of years, we want to honour that legacy and work together with that kaupapa. Land and people can not be separated so we work to respect the people that came before and will come in the future.


We care about our people and the land we work with. The wellbeing of our people and our community is central to our operation. Whenua has mauri (energy), we are innovative kaitiaki (guardians of the land) and we work with whanaungatanga (together with our clients and suppliers).


We are one big team – our staff, clients and suppliers. We are community. People are important to us and we work hard to build strong relationships at every level. These relationships are based on respect and a commitment to retaining and protecting everyone’s mana.


We feel the fear and do it anyway. We challenge ourselves if we need to and with that we grow. We push ourselves in every situation and by being anchored to our true north, we know how a situation should be addressed. We empower our people through autonomy.


Best in everything we do. We apply and share our knowledge and expertise. We focus on understanding our clients’ needs and solving every problem to the highest of standard. We are reliable, accurate, 100% accountable and proud of our underlying belief in ourselves.
