Building Estimation Solutions for

Residential & Commercial Builders

Auckland and Wellington

Dear Local Builder,

Want to Gain Complete Control Over Your Projects and Save Thousands?

Newin’s established service specialises in assisting residential and commercial builders across Auckland and Wellington who may not have the expertise, time or resources to conduct detailed costing for clients or deliver superior project management services.

As leading industry experts, Newin is a preferred and trusted partner choice that can help you manage and grow your building business dramatically.

Through our smart outsourcing solutions, we’ll work alongside your office to deliver fast and accurate project cost estimates, and even project management support, saving you time, resources, and $$. 

So why not contact us for a no-obligation meeting today and see how we can make your business better.

The No 1 Reason to Outsource Your  Cost Estimates

It’s simply…Better Risk Management


You’ll get to tap into our 18 years of trusted industry experience and specialist approach to delivering highly accurate cost estimates and quantity surveys.  You and staff may not have time to stay up-to-date with the latest market rates…but we do.

Excellent ROI

 With our expert guidance, Newin typically help clients save 10 – 15% on their construction costs – which could mean an extra $30,000+ in your pocket.

Save Time & Money & Internal Resources

You won’t have to worry about training staff or the risk of inaccurate reports. We’ll help reduce your in-house admin time and costs significantly.

All Types of Projects

We’ve built a team that has solid experience over a range of projects; commercial, industrial or residential construction projects.

Higher Cost Accuracy

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

Gain Time & Grow Your Business

Do you want more time to grow your client base or simply want to be freer? Imagine how many hours a week you will save if you didn’t have to worry about the cost estimation side of your business.

Affordable Fixed Price

It is time consuming and costly to manage internal staff and potentially rework errors. If you “had to cost the time per report” it could be thousands. By outsourcing you benefit from a fixed cost per proposal and perhaps mostly importantly, one that is highly accurate. Our cost plans start from $990.

Are you at risk of underquoting jobs?
Underquoting in the building industry is a common issue and is usually the result of several mitigating factors, with the most common being a lack of detail in budget planning

Newin creates project costings based on current market prices and rates and account for every detail. Complete breakdowns are provided to ensure full transparency.

We believe that detailed accurate budgets are the only way to ensure you maintain complete fiscal control over the life cycle of the project.

Are you looking for cost-effective expertise to better manage projects and without hiring staff?
As a builder, taking time out to manage projects, subcontractors, and budgets may not be the best use of your time, and the expense of hiring more staff may not be a viable investment for your business.

We are established and can bring knowledge and experience to your project without the expense of full-time staff.

Are you struggling to manage your projects on time and to budget?
Full trade breakdowns related to the category of construction required to complete the work ensure your project does not enter the construction phase until an accurate and detailed budget has been compiled.

At Newin, we know that accurate, detailed, and complete budgets covering every stage and aspect of the project is the only way to ensure financial obligations can be met as the project progresses through its various stages and scopes of work.

For your peace of mind, Newin is also able to provide ongoing support to the project team and ensure they are fully equipped to manage and control project and trade costs at all stages of the development.

Do you want to improve your success rate at winning more building jobs?
Undercutting on quotes or providing quotes that do not adequately cover the real cost of a job will only ensure you receive a poor reputation in the market.

A key aspect of winning more building jobs and maintaining your excellent reputation is to ensure every quote covers all aspects of the job, accounts for every detail, and reflects true market value.

Using Newin for all your project budgets will ensure that each quote your client receives provides the best value, while also removing the risk of underquoting.
