The funding for this project is under the New Zealand Infrastructure Trust Fund (ITF). The overall cost has grown since the estimated $5,750,000 New Zealand Dollar (NZD). This is due to increasing material costs as well as new inclusions that have been identified from having better recognition of the development and capacity required. Through consideration of key preliminary consultations, internal reviews and re-reviews, working and reworking of the concept design approach and relative cost packaging options, the budget proposed is now $7,600,000 (NZD). This budget was approved by the ITF steering committee in November 2022.
