Site Manager - New Build Service Station

Jora New Zealand will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey. Site Manager - New Build Service Station Mansfield Group – Christchurch, South Island When backup power can't fail, Mansfield delivers. We're a family-owned business with 60+ years of experience installing and maintaining diesel generator fuel systems for the organisations that can't afford downtime, healthcare, telecommunications, transport infrastructure, and government facilities. We're small, direct, and accountable. You'll work with the same team from planning through to handover. Our clients include national telco providers, critical infrastructure, and health providers who trust us precisely because we stay close to the job, solve problems early, and own the outcome. ROLE PURPOSE The Site Manager is responsible for the day to day running of a new build service station project on behalf of Mansfield Group. This role owns the site from mobilisation through to handover, coordinating trades, subcontractors, and suppliers to deliver the works safely, on programme, and to the standard our clients expect. The Site Manager is the main point of contact on site and is accountable for health and safety, quality, and progress reporting throughout the build. KEY RESPONSIBILITIES Take full responsibility for site operations on a new build service station, from site establishment through to practical completion and handover. Plan, coordinate, and supervise all on site trades and subcontractors, with a strong focus on civil works (earthworks, excavation, concrete, underground services), plus fuel system installation, electrical, and building works. Manage the site programme, track progress against milestones, and elevate delays or risks early. Enforce site health and safety requirements in line with HSWA 2015 and Mansfield Group site procedures, including inductions, toolbox talks, and hazard management. Carry out and record quality checks against drawings, specifications, and relevant NZ standards (including fuel system and tank installation requirements). Manage deliveries, plant, and materials on site, and keep the site secure, tidy, and compliant. Liaise directly with the client, principal contractor, engineers, and council or regulatory inspectors as required. Hold regular site meetings and provide clear progress reporting back to the Mansfield Group project team. Manage variations, RFIs, and site instructions, and keep accurate daily site records. Support commissioning and testing of the fuel system and associated infrastructure ahead of handover. Mentor and manage site labour, including any apprentices or junior staff assigned to the project. EXPERIENCE AND QUALIFICATIONS Required: proven track record managing civil works on commercial or infrastructure new build projects, including earthworks, excavation, concrete, and underground services. Required: proven experience as a Site Manager or Site Supervisor delivering projects from mobilisation through to handover, minimum 3 years. Preferred: experience with fuel system, service station, or tank installation work. Sound working knowledge of NZ building and construction standards, HSWA 2015, and site safety management systems. Experience managing subcontractors and multiple trades on a live construction site. Site Safe/Construct Safe certification (or willingness to obtain) and a current New Zealand driver licence. Relevant trade or construction management qualification is an advantage, but not essential with sufficient site experience. Experience with dangerous goods, hazardous substances, or fuel handling requirements is highly regarded. SKILLS AND ATTRIBUTES Strong leadership and the ability to keep a site team focused, safe, and on programme. Clear communicator, comfortable dealing with clients, consultants, and regulatory bodies. Well organised, with good attention to detail on quality and documentation. Practical problem solver who can make sound decisions on site under pressure. Committed to health and safety as a genuine priority, not a compliance exercise. WHAT MANSFIELD GROUP OFFERS The chance to lead a significant new build project from the ground up. A supportive team environment backed by an established fuel and power infrastructure company. Competitive remuneration based on experience. Work vehicle, work phone, and tools of trade provided. #J-18808-Ljbffr
