Who Are We?

Are you looking for a highly accurate building cost estimating service partner in Auckland?

Hi, I’m Hai Nguyen, founder of Newin Building Estimating Services.

I started this business with the vision of supporting my industry colleagues improve their costing process and estimates.

I see it happen all the time – from inaccurate costings and lack of expertise and time, all which lead to losing clients and money.

At Newin Building Estimating Services, we do costing differently!

Unlike other agencies, we don’t use cost guides as we don’t find them reliable. We believe in digging much deeper to give you concrete data and rates, meaning you’ll feel secure with your budgets and the decisions you make.

With offices across Auckland, New Zealand as well as Sydney and Melbourne, Australia, and powered by 10 year’s + experience in the construction industry, we have proudly become a partner of choice for leading builders, architects, designers and developers.

We pride ourselves on being hands-on, affordable and eager to share ways on how we can support your business.



Our client-focused services include:

  • Building cost estimation reports.
  • Quantity surveying services and BOQ reports through all phases of construction, meaning “no surprises”.
  • Project Management expertise support for builders to help you stay on track and budget.
  • Custom-made building consultancy services for commercial, industrial and residential construction projects. Call us for a chat?
  • We understand budget is important to your profitability. Our cost plans starts from NZD$800+GST.
