Ruamahunga Bay Joinery is dedicated to working with high quality, environmentally friendly timbers, recommending native and imported timbers from sustainably managed forests or using recycled timber.

The benefits of this are many. Firstly, recycling is good for the environment. Secondly, NZ natives such as Kauri, Matai, Totara and Rimu are renowned as being amongst the finest joinery-grade timbers in the world, and aesthetically they are without equal. Thirdly, the cost is substantially less than new, non-plantation timber.
