What is a Quantity Surveyor?
A Quantity Surveyor (QS) is responsible for forecasting, managing, and controlling the financial aspects of a construction project. Their role is to provide accurate cost planning from early feasibility through to final account, ensuring projects remain financially sound and aligned with budget expectations.
Quantity surveyors are construction cost specialists who measure, estimate, and monitor the cost of labour, materials, and resources. They support informed decision-making, manage variations and contractual changes, and help resolve cost-related matters between parties, keeping projects on track, on budget, and commercially well managed.
Our Process

CM-NZ is a member of the New Zealand Institute of Quantity Surveyors. Our team includes Registered Quantity Surveyors with experience across commercial, residential, education, and public sector projects.
This ensures our advice meets recognised professional standards, stands up to independent review, and protects your reputation.
Technology that supports accuracy
We use RIB CostX estimating software to support precise measurement and pricing. This allows us to deliver detailed digital take-offs, consistent cost plans, and reliable reporting.
Technology supports our work, but judgement drives it. Every output is reviewed through a practical construction lens to ensure it reflects real-world conditions and market realities. The result is disciplined financial control and stronger project outcomes.
