• Macadamia trees have similar soil and climatic requirements to avocado trees and are a suitable replacement crop for avocados. Macadamias originated in subtropical eastern Australia, Indonesia and New Caledonia.
  • Macadamia tree takes five to twelve years to produce nuts and a good tree can produce nuts for 40 years. The trees require a hot subtropical climate without much humidity. Macadamias are now widely used in the confectionery, baking, ice cream and snack food industries.
  • Macadamia oil’s rich, cushiony skin feel and high oxidative stability make it especially suitable for heavy creams and sun care formulations. Medical research has shown that the consumption of macadamias may significantly lower the risk of heart disease.
  • Macadamia nuts have a sweet taste and are a super source of energy. They also contain large amounts of vitamin A and iron, as well as zinc and calcium.
  • Raw macadamias have been awarded the South African heart mark as an approved part of the Heart and Stroke Foundation healthy eating plan. They can be eaten raw or roasted.

International business environment

  • South Africa, Kenya and Australia are the largest producers of macadamia nuts.
  • The Southern African Macadamia Growers’ Association (SAMAC) works closely with other African macadamia producing countries like Kenya and Malawi, also major macadamia producers, and Zimbabwe. Macadamia nuts are also grown in Brazil, United States of America (especially Hawaii), Israel, China, Swaziland, New Zealand, Colombia and Guatemala.
  • SAMAC is a member of the International Nut and Dried Fruit Council (INC). Visit www.nutfruit.org.

South Africa: imports and exports

There is an export standard on all inshell macadamia nuts, which means every consignment is inspected by the Perishable Products Export Control Board (PPECB). Download the standard at www.samac.org.za/standards/.

More than 98% of South Africa’s macadamia produce is exported. According to figures received from the South African Revenue Service, the total value of macadamia exports in 2019 was R4.8 billion. A breakdown of exports is included among the information at www.samac.org.za/industry-statistics.

A Profile of the South African Macadamia Nut Market Value Chain (see “Websites & publications” heading) also looks at macadamia nut exports and imports.

Local business environment

  • KwaZulu-Natal (39%), Mpumalanga (36%) and Limpopo (21%) are the major production regions in South Africa.
  • When the growth by the number of trees sold is taken into consideration, approximately 44 775 ha of macadamias have been established in South Africa. Macadamia production has increased dramatically and the rate of production is expected to increase even more in the near future due to an exponential increase in new plantings annually.
  • Some 700 farmers grow macadamia nuts. Several of these are GlobalGAP and SIZA accredited and most cracking facilities are HACCP and/or ISO 9001 accredited. This ensures full traceability for customers and supplies fast feedback to farmers of quality.
  • Some 13 857 full-time workers are employed in the macadamia industry, 12 684 of these on macadamia farms. An additional 13 647 seasonal (temporary) workers help when harvesting and processing happens (February to August).
  • The total value of annual production has increased from R32 million in 1996 to approximately R4.8 Billion in 2019.
  • Information on cultivars, kernel recovery, historical macadamia production figures and more can be found at www.samac.org.za/industry-statistics.

National strategy and government contact

Macadamias are an important crop for the country, having high-growth-potential while also being labour intensive (Sihlobo, 2018). The National Development Plan singled out the nut sector as one of the smaller, labour- intensive industries with huge expansion and labour creation potential. The BFAP Baseline 2019 noted that pecans and macadamias were among those industries that have already expanded beyond the targets of the NDP (BFAP, 2019).
