T.N.H. Fencing was established in 1990. Based in Johannesburg, the company focused mainly on supplying and installing security fencing in the P.W.V. area. At the time, there was also a demand for electric fencing products from other African countries, so T.N.H. exported materials to countries such as Zimbabwe, Malawi and Zambia. There was however a growing need in rural areas for service-orientated organizations with knowledgeable personnel to install good quality electric fences on farms and game reserves. Identifying this demand, T.N.H. changed the focus of the business in 1995 to supplying and installing fencing for the agricultural and expanding wildlife markets.
The North-West had become a popular wildlife destination and T.N.H. was contracted to electrify the fences of both Madikwe Game Reserve and Pilanesberg National Park. T.N.H. built bomas in Madikwe to facilitate the introduction of elephants, lions and wild dogs to the reserve as part of "Operation Phoenix", Madikwe's massive wildlife relocation programme. Since then, the company has focused on supplying and installing top quality game fences throughout Africa. While not only advising, training installing and maintaining fences for national and international conservation organizations such as W.W.F. in Uganda, South Africa and Malawi, T.N.H.'s clientele also includes numerous Southern African farmers, game ranchers and game breeders. Some of the better known South African game ranches where T.N.H. has worked include Lapalala Wilderness Reserve, Tswalu Kalahari Reserve, Glen Lyon, Venetia and Marakele. The company has also conducted electric fence training courses for conservation staff in Botswana, Zimbabwe, Malawi, Uganda and South Africa.
After completing his schooling in his native Rhodesia (now Zimbabwe), Tubby began his working career as a dairy and beef cattle farmer. From there he trained as a veterinary technician and spent the next few years traversing the Rhodesian bush in the employ of the state veterinary services. Upon moving to South Africa, Tubby joined Coopers Animal Health in the Natal midlands where he sold veterinary products. Tubby then moved to Gallagher-Poldenvale, where he was the national sales manager. The company not only supplied farmers with stock handling equipment, but also with Gallagher electric fencing products. It was there where Tubby was first exposed to electric fencing and the potential it held for managing both game and domestic livestock. Bill Gallagher, who had developed the Gallagher product after his father started the business in the 1920's together with the late Ray Metcalfe were largely responsible for Tubby's training in electric fencing. It was under their tutorage as well as that of Maurice Williamson of Stafix that Tubby obtained his extensive knowledge of electric fencing. In 1990 he formed T.N.H. Fencing.
