In the late 60s, 70s and 80s, Neal & Massy grew rapidly both locally and regionally. One of the major focal points at the time was Guyana where the company first invested in engineering agencies. The Group started business in Guyana in 1968 when its subsidiary, Associated Industries Limited, was incorporated. The company became the distributor for Tracmac products and the Bandag tyre re-treading operations. Associated Industries in Guyana acquired a majority holding in the Demerara Oxygen Company Limited (DOCOL) in 1975. The Group also expanded into Suriname and reached as far as Belize, giving the Neal & Massy Group probably the furthest reach at that time, spanning the entire Caribbean Basin. In 1979, Neal & Massy Suriname was formed. Presently, Guyana remains the only South American country in which the Group is involved.
In 1988, the Group’s four companies in Guyana were Associated Industries, Demerara Oxygen, Transportation Services and Demerara Property Investments. NM Services Limited was created during the re-structuring of the company in 2000. It offered vehicle leasing, equipment finance, customs brokerage and Moneygram. Today, Neal & Massy Limited is the holding company for the Guyana Group, which comprises 6 companies: the original Associated Industries Limited, CCS Guyana Limited; Demerara Oxygen Company Limited; Geddes Grant Guyana Limited; NM Services Limited and Securicor Limited.
