The project includes a new Grid Exit Point (GXP) at Cuttance Road, a 110kV overhead line connecting the GXP to a new substation at Fonterra’s Edendale site, and associated access roading. This infrastructure will increase electricity capacity in eastern Southland, improve network resilience, and support Fonterra’s transition away from coal-fired process heat through the introduction of electric electrode boilers and other site upgrades.
Bonisch is providing integrated planning, surveying, and engineering services across multiple stages of the project, from early development through to construction. Our involvement includes resource consenting and cadastral surveying for the subdivision of the GXP lot, design and construction support for the GXP access road, and surveying services for design, construction set-out, as-built information, and easement definition along the transmission corridor.
The Hokonui Line forms part of a broader investment in Southland’s future energy infrastructure, supporting industrial growth, network resilience, and decarbonisation objectives. Delivering a project of this scale requires coordination between electricity network operators, landowners, contractors, designers, local authorities, and a major industrial customer. The transmission corridor traverses rural properties and road reserves and includes significant infrastructure such as the new GXP facility, associated access upgrades, and a 110kV overhead line supported by large steel poles.
With planning approvals, land transfer requirements, road design, procurement, construction, survey set-out, and easement establishment progressing concurrently, maintaining alignment across project workstreams has been critical. Close collaboration between stakeholders and technical disciplines ensures land requirements, approvals, design decisions, construction activities, and long-term asset protection measures are coordinated throughout delivery.
Bonisch’s Planning team has supported the approvals pathway for the GXP site, including the subdivision required to create the GXP lot from the surrounding farmland. This work established the planning and cadastral framework needed to enable development of the new electricity infrastructure.
Our Surveying team has provided topographical surveys, construction set-out, as-built surveys, and easement definition services to support both design and construction. The establishment of easements is a key component of the project, securing long-term protection of the transmission corridor while balancing the interests of affected landowners.
The Engineering team has delivered design, procurement, and construction support services for the GXP access road, including tender documentation, contractor engagement, and construction monitoring. The team has also supported the wider transmission line works through contract administration, independent certification, procurement documentation, and construction support.
By combining expertise across Planning, Surveying, and Engineering, Bonisch has provided a coordinated service that streamlines project delivery and helps maintain consistency across all stages of development. Technical, planning, and land-related requirements have been integrated into a single delivery approach, allowing information and decisions to flow efficiently between disciplines and stakeholders.
The Hokonui Line demonstrates the value of a multidisciplinary approach to complex infrastructure projects. Through coordinated support across planning, land development, design, procurement, surveying, and construction, Bonisch has helped maintain alignment between stakeholders, approvals, and delivery requirements. The project will play an important role in supporting Southland's future energy needs, regional economic growth, and the transition to a lower-carbon future.
