About RJ Mac Contracting
Local Brothers. Built for the Land.

Proudly Based in Marlborough
RJ Mac Contracting is owned and operated by brothers Ryan and Justin Macdonald - born and raised right here in Marlborough. Growing up on the family farm, early mornings, heavy machinery, and hard work were simply part of life. That upbringing shaped the practical, hands-on approach they bring to every job today.
​
What began as a small operation has grown into a trusted name across the region. From rural paddocks to subdivision developments, the RJ Mac team is known for turning up, getting stuck in, and doing the job properly.
With a yard full of machinery, decades of combined experience, and a tight crew behind them, the brothers have built a business they’re genuinely proud of - one that remains firmly rooted in the place they call home.

Local Roots, Strong Relationships
Ryan and Justin have deep connections throughout Marlborough, built through years of work, family, and community involvement. In a region where word of mouth matters, they’ve earned trust by being consistent, easy to deal with, and committed to supporting the people who support them.
Extensive Expertise
From small one-off jobs to large earthworks projects, the team brings a wealth of practical experience to every site. Their background in farming, land development, machinery operation, and problem-solving ensures each job is done efficiently and to a high standard.
Reliable and Accountable
Showing up, doing what they say, and standing by their work - that’s the RJ Mac way. Clients value their honesty, communication, and no-nonsense approach. When the team commits to a job, they follow through from start to finish.
Our Commitment
Building a Stronger Community
Marlborough is home, and the Macdonald family is proud to contribute to its growth. As they raise their own families here, they’re focused on delivering work that supports local development and creates opportunities for others. Every project - big or small - plays a part in strengthening the region for the next generation.
