Quality Products

At Promax, quality is everything.

Our entire team is focused on combining exceptional design with manufacturing excellence to bring you a comprehensive range of products that look good and work even better. 

Not only are our products the best on the market, but our service is impeccable as well.  Our experienced Sales and Customer Service teams know that you will have specific requirements and we’ll  work with you to ensure you get the right products for your project. In particularly challenging situations and locations, our specialist engineers can even help you with a custom design.  We also understand that prompt delivery is very important. Our North and South Island Dispatch teams work diligently to ensure your products arrive as quickly as possible, and in top condition. 

All Promax tanks are certified to AS/NZ 4766 and our detention tanks are fully tested and designed to withstand ground and water pressure, even at depth. The Promax Underground Tank is engineered by geotechnical experts and Finite Element Analysis tested (FEA). Our tanks are so strong they are the only plastic water tanks in New Zealand that can be buried up to one metre and still retain a 20-year warranty! 

We’re proud of everything we do, but don’t just take our word for it.  In a recent survey, over 80% of our customers said they would recommend Promax to others because of our excellent customer service. Here’s what a few of them had to say: 

“They are absolutely superb. I will be recommending them.” - Selwyn Boler, Wellsford 

“Dealing with Promax was a breeze. The pricing was more than competitive, the salespeople professional and very obliging and the communication regarding delivery, choice of colour and sizes was second to none.” – Sean Allen, Gisborne 

Promax is also authorised to use the BSI registered Benchmark Product Certification Trademark, on products identified in the Product Certification Schedule. You can view this here.
