What RotoTank does
RotoTank is a New Zealand-based plastic manufacturing business that produces rotational-moulded polyethylene water storage products for residential, lifestyle-block, agricultural, and recreational-vehicle customers. Its portfolio spans small-format 200-litre barrels through to its largest in-house tank at 7,500 litres, complemented by 360-litre and 750-litre livestock water troughs, a dedicated caravan/motorhome tank range (70/100/150 litres) with baffles, and a referral pathway via Devan Tanks for 10,000–30,000 litre capacity tanks. All tanks are manufactured in Ashburton using food-grade UV-stabilised polyethylene compliant with AS/NZS 4020:2002 (drinking water) and AS/NZS 2070 Part 1 and 8 (food contact) standards and carry a 10-year workmanship and materials guarantee.
The company's go-to-market is direct-to-customer via its website and a single phone line (03 308 4497), with sales enquiries handled by Sandra Lamont. There is no intermediary distribution network; orders are taken at the Ashburton factory and shipped directly. RotoTank also operates as a contract manufacturer for commercial plastic rotational moulding customers, a stream that has reportedly grown to roughly half of total business under the parent entity Rotowiper Limited. The legal entity Rotowiper Limited was formed by Dougal and Jenny Lamont, who acquired their partner's shares in 2018 and merged the predecessor companies (Rotowiper Limited and Mouldings SI Unlimited) into the present structure. The company has 11–50 employees, is privately held with no institutional or external funding, and operates solely within New Zealand.

RotoTank competitors and assessment
Company assessmentDirect peers
- Enduramaxx: UK-based rotational moulding manufacturer of plastic water tanks, chemical tanks, and custom mouldings. Equivalent in manufacturing process and product type, though operating in a different geography.
- Bushman Tanks: Australian manufacturer of plastic water tanks using rotational moulding, serving residential, rural, and commercial segments. Directly comparable in product type, manufacturing process, and target customer, though primarily focused on the Australian market.
- Polymaster: Australian manufacturer of polyethylene water tanks, troughs, and trailers. Highly comparable in product range (residential, agricultural, RV) and rotational moulding manufacturing process, with significantly larger scale and broader distribution across Australia.
- National Poly Industries: Australian polyethylene products manufacturer producing water tanks, agricultural products, and custom rotational moulded items. Comparable in both own-brand tank products and contract rotational moulding services.
- Devan Tanks: New Zealand-based plastic water tank manufacturer headquartered in Morrinsville, producing a wide range of poly tanks up to 30,000L. Already a referral partner to RotoTank for tanks above 7,500L, and a direct competitor in the residential and lifestyle block tank segments across NZ.
Broad incumbents
- Rotoplas: Latin American plastic water storage and fluid handling solutions company with operations across multiple geographies. Broader incumbent in plastic tanks, providing scale and geographic reach that RotoTank lacks.
- Kingspan Water & Energy: Global leader in water storage solutions including plastic and steel tanks, with a comprehensive product range and established distribution networks. A broader incumbent that competes with RotoTank in commercial and larger-capacity segments.
- Sintex Plastics: Indian manufacturer of plastic water tanks and storage products with a global distribution footprint. Comparable in core product (plastic water tanks) but at substantially larger scale and broader geographic reach.
Regional players
- Promax Plastics: New Zealand plastic product manufacturer producing tanks and other rotational moulded items. A regional competitor in the NZ tank market with overlapping product categories.
Emerging players
- Devan Plastics (AU): Australian rotational moulding specialist offering custom moulding services and limited own-brand products. Comparable as a contract rotational moulding peer, particularly relevant given RotoTank's ~50% contract manufacturing revenue mix.
