SubsQS Limited is a builder-led quantity surveying and construction estimating firm based in Rotorua, New Zealand. With over 19 years of hands-on experience in the building industry, we offer a unique blend of trade-level insight and professional quantity surveying expertise. Our mission is simple: to help builders, subcontractors, developers, architects, and homeowners quote confidently and build profitably.
At SubsQS, we understand that accurate estimating is the backbone of every successful construction project. Whether you're pricing a labour-only contract, preparing a full tender, or needing cost plans for finance approval, we deliver detailed, practical estimates that reflect real-world costs. Our builder-first approach ensures every number we provide is grounded in practical knowledge — not just spreadsheets.
We specialise in a range of construction cost services, including feasibility estimates, bank-ready cost plans, material take-offs, labour-only pricing, and tender preparation. Our reports are clear, concise, and tailored to the New Zealand construction market. From small trade jobs to multi-unit developments, we work closely with each client to deliver the insights they need to price accurately and protect their margins.
Our services are trusted by a wide range of professionals:
-
Builders needing fast, accurate costings for fixed-price or labour-only jobs
-
Subcontractors looking to streamline their quoting and win more work
-
Developers and architects seeking early-stage feasibility or funding estimates
-
Homeowners who want independent, professional advice on renovation or new build costs
We proudly serve the Bay of Plenty, Waikato, Auckland, and Central North Island regions — including Tauranga, Mount Maunganui, Omokoroa, Hamilton, and Taupō. Remote delivery options make it easy for clients across New Zealand to access our services, no matter where they’re building.
What makes SubsQS different is our background: we’ve built houses, not just estimated them. We understand the pressure of quoting jobs quickly and the real impact of a missed cost on site. That’s why our clients value our clarity, speed, and honesty — and why so many tradespeople return to us again and again.
We don’t just deliver documents — we support your business. We help you:
-
Identify scope gaps and cost risks
-
Understand project margins
-
Prepare professional tenders
-
Communicate clearly with clients, banks, and consultants
All estimates are prepared in-house by qualified professionals who’ve been on the tools and now work full-time in cost consulting. We use proven systems, consistent pricing models, and builder-friendly language to make sure you get the clarity and confidence you need.
Whether you’re a solo tradie or a growing construction business, SubsQS is your trusted partner in building smarter. Let us take care of the numbers — so you can get back to the tools.
