Regional consents from Northland Regional Council and land use consents from Whangārei District Council were required to enable the expansion. To support the resource consent applications, Boffa Miskell prepared landscape and visual assessments.

The application sought new resource consents to authorise the redevelopment of the Wilsonville quarrying pit, including overburden placement and increased water take and discharge operations. Associated activities included the removal and placement of overburden, resource extraction, the taking of groundwater, and the discharge and diversion of stormwater associated with on-site sediment ponds.

Consents were granted in 2024. Following this, Boffa Miskell was engaged to help protect the quarry from the effects of a neighbouring subdivision proposed along the quarry boundary, managing reverse sensitivity issues associated with the incompatible land use. This included a hearing process where Boffa Miskell provided expert evidence. The proposal was ultimately appealed to the Environment Court, where a mutually acceptable outcome was reached through mediation.
