About Us


NZ Grinders provides concrete polishing and concrete grinding for domestic, commercial, industrial, and agricultural clients New Zealand wide.

Since its founding, NZ Grinders has earned its reputation as a contractor that provides stunning high fashion and architectural flooring solutions. NZ Grinders success is grounded in the company’s dedication to the success of its clients and its people.

We use the latest equipment, with eco-friendly and sustainable processes, so we can cheaply and effectively polish large areas of floor in very little time, whilst reducing our carbon footprint and being kind to the environment.

A key component of our success is our technically-advanced grinding machines. From our small HTC 270 edger to our mind blowing ride on 1.9 ton grinder which can deliver 1500 SQ/Metres of hard grinding in 1 day, leaving the floors flatter than any other grinder on the market. We have the equipment and expertise to provide an excellent service with the speed and precision that no other NZ polishing company can match.

We have built our reputation on the great service we provide, ensuring safety and quality are not compromised in any way. We have developed firm relationships with our customers and pride ourselves in our friendly and efficient service and we ask that our staff help in a positive way to provide a great experience so that customers are delighted with our service.

The Company’s philosophy is strong operating out of our core values of integrity, respect and teamwork. We celebrate and encourage participation and engagement. Together we have a common goal of ensuring the business is operating as effectively and efficiently as possible to produce the best results.

We adopt best practices and our work environment favours honest communication and acting with integrity.

From small domestic jobs, up to large scale industrial sites, we have the equipment and expertise to provide an excellent service with the speed and precision that no other NZ polishing company can match.

This technology, combined with the intense attention to detail of our staff, means we can deliver super high-quality results with very fast turnaround times.
