With over 30 years of experience in the Concrete and Construction Industry, both in New Zealand and overseas,

Justin Robb is the driving force behind Precast Products Limited.

Upon returning to Bay of Islands in 2016, Justin had a vision to create innovative, functional, and durable concrete products. 

In 2017, Precast Products Limited was established, and together with his partner Sandra, they have been designing and crafting concrete products to enhance the lifestyles of New Zealanders. 


From Livestock Troughs to Smokehouses and Concrete Pavers, and all our other items, each product is meticulously handmade on site and tailored to order. 


We take pride in using the highest quality raw materials and fibre to create our concrete mix designed for superior strength and durability.

One of our standout products is our Livestock Troughs, which have an innovative design and hold a New Zealand Patent (NZ Patent 755783). 

They are the cornerstone of our Rural Product range. 

We also offer a complementary product called the Paddock Podium®  (NZ Patent Application # 790756), designed to fit inside a trough without affecting the water level. Easy to use and transport, it can be customised to fit any trough style. 

Its primary purpose is to prevent accidental drowning and save livestock lives.

As our product range continues to expand, we are always on the lookout for new additions.
