We’re excited to share that 3Capital has invested in Earth Stability, a New Zealand specialist contractor with an established reputation in ground stabilisation, slope protection and complex geotechnical works.
Founded in 2012, Earth Stability has built a strong reputation for delivering technically challenging projects across New Zealand. Its specialist capabilities span slip repairs, rockfall protection, ground anchoring, soil nailing, retaining structures and difficult-access construction, often in environments where conventional construction methods aren’t possible.
Over more than a decade, Earth Stability has established itself as a trusted contractor, backed by an experienced team, specialist technical expertise and a proven ability to deliver complex projects.

“Earth Stability is exactly the type of business we look to partner with. They’ve built a strong reputation in a highly specialised area of construction, backed by a capable team, technical expertise and a proven track record of delivering challenging projects.
As a construction-focused investment business, we see real value in partnering with companies where we understand the industry and can contribute more than just capital. We’re excited about the opportunity to work alongside the Earth Stability team, build on what they’ve already achieved and support the next stage of their growth.”
- Mark Duffin, 3Capital
