Blenheim, Marlborough, New Zealand Isaac Group Full time NZ$120,000 - NZ$180,000 per year

About the Role: We're looking for a senior civil construction leader to join our team at Simcox Construction (part of the Isaac Group), based in Blenheim and delivering across the wider Marlborough and Kaikōura regions.

As Construction Manager, you will play a key leadership role supporting the Regional and Operations Managers to drive project delivery excellence, mentor and grow our emerging project management talent, and contribute to securing future work. This is a hands-on role in a lean but high-performing team, ideal for someone ready to make a real difference — both on the ground and in long-term capability building.

You'll also collaborate regularly with our other four regional bases across the South Island, backed by Isaac Group's strong support functions in Christchurch.

Why Join Us:

  • Make a strategic impact: Help close a senior leadership gap and develop our Project Managers.
  • Deliver award-winning projects: We lead complex works from $5M to $30M+, including design-build and alternative delivery methods.
  • Leverage our vertical integration: Simcox has unmatched in-house local Marlborough capabilities – including quarries, cleanfills, surfacing, GPS plant, survey & design, transport fleet, traffic management and more.
  • Enjoy the Marlborough lifestyle: Work, live and play in one of NZ's sunniest regions – a brilliant place to raise a family, explore the outdoors, and escape city congestion.

Key Responsibilities:

  • Contribute flexibly within our lean management team – this is a hands-on leadership role.
  • Lead involvement in tendering, pricing, and strategy for new work.
  • Mentor and support project managers in all aspects of delivery, including commercial management and contract leadership.
  • Guide continuous improvement across construction quality, delivery innovation, and safety performance.
  • Engage with clients, consultants, subcontractors and local authorities to strengthen relationships and uphold our reputation.
  • Coordinate Blenheim Construction P&L monthly reporting and analysis.
  • Take a leading role in promoting excellent health and safety, quality, environment and productivity cultures in the Simcox Construction crews. Contribute to continuous improvement of our HSEQ Systems.

About You:

  • Proven senior project management track record in civil construction, ideally with experience managing departments or regions.
  • Strong commercial acumen – able to lead tenders and price projects upwards of $15M.
  • Deep experience mentoring and developing project managers and site leadership.
  • Excellent interpersonal and relationship-building skills – grounded, collaborative, and confident.
  • Willingness to "roll up sleeves" and support where needed across operations and leadership.

What We Offer:

  • Competitive salary + vehicle 
  • Medical insurance
  • Career growth & training pathways
  • Supportive, family-oriented team culture
  • Opportunity to shape a growing region and team

Who We Are:  Simcox Construction has served the Marlborough region since 1984 and became part of the Isaac Group in 2018. The Isaac Group has been building civil infrastructure across the South Island since the 1950s — combining construction excellence with environmental stewardship through our unique Conservation and Wildlife Trust.

We have a dedicated Learning and Development team, and we invest heavily in people's career development and are proud of our tight-knit teams and high-performance culture.
