John Berry Founder, Chemz Ltd
“When I was approached over 20 years ago by Kiwi businesses desperate for a home-grown industrial aerosol range, I only had two guiding principles. Firstly, Chemz would provide the market with quality products. Secondly, I would continually innovate and work with industry to develop products that were actually needed.

These principles continue to drive our successful business model and allows Chemz to work closely with our industry partners and distributors to exceed market expectations with a 100% Kiwi owned company.”

Our Story

John Berry has been working in the petroleum industry for over 40 years. In the 1990’s his experience in the sector in both Australia and New Zealand enabled him to work with NZ distribution companies who were desperate for an alternative, quality aerosol company who didn’t lock them into significant trading restrictions.

In 2000, Chemix was born. John entered the market with a New Zealand first – a quality range of ‘3in1’ oil in an aerosol can. The market responded with gusto.

Chemix grew into Chemz, picked up pace and launched a suite of ‘first to market’ innovative products specifically designed for Kiwi businesses.

Fast forward over 20 years and Chemz has a range of over 60 market specific products including a full food grade range, automotive, industrial, electrical, marker sprays, sanitisers and a ‘nextgen’ collaboration as products are constantly refined and improved.

Chemz remains a 100% Kiwi family business, with John’s daughters Tiffany Berry and Prue Berry joining the company in late 2021 as directors and shareholders, adding value in the portfolios of governance, strategy, planning and finance.

Our Quality

Chemz stands by its reputation for technical excellence. Every can that comes off the production line is fully quality controlled and every formulation is tested and re-tested to ensure it will do the job it was designed to do.

Every step of production is monitored to ensure that a Chemz can performs and provides value for money. This quality assurance means you can confidently rely on a Chemz product to perform to standard every time. Chemz works with industrial chemists who are leaders in their field and who listen to the market, developing formulations to meet the specific requirements of New Zealand industry.

With a focus on quality outcomes, Chemz never compromises on production or material cost. Instead Chemz concentrates on strong Kiwi supply relationships where quality is valued as a moderator in a market dominated by overseas multinational companies.


Our Sustainability

Chemz has long been committed to environmentally conscious operations as a business model. NextGen is a collection of Chemz products which create less negative impact on people and the environment. Chemz also makes conscious decisions to use sustainable manufacturing practices wherever possible, including raw product sourcing. It actively participates in comprehensive recycling programmes and has implemented continual energy and water consumption reduction strategies in its production line.

The unique benefit of using Chemz products is the contribution to decreasing manufacturing miles. The closer to home a product is made, sold and used, the less negative impact on the world’s carbon footprint and greenhouse gases.

By supporting a local industry like Chemz, kiwis can significantly reduce manufacturing miles and actively participate in New Zealand’s commitment to be carbon neutral by 2050.
