Step 4 Mahi Hangarau (technical work) refers to the detailed technical design, drawings, options and associated costs necessary to progress and confirm the Trust’s papakainga proposal. The Trust’s proposal is likely to be revised several times in response to the key technical issues for the papakainga proposal before it is supported and approved by the owners and the local authority. Each papakainga site will have its own unique physical characteristics with its own challenges and opportunities that the Trustees will need to address and resolve. “Nga mahi hangarau” will assist the Trustees in identifying what the key technical development issues are for the papakainga proposal and what further information may be needed to assist the Trust and owners to make the best decisions for the overall papakainga development proposal.
