A large number of residents from New Brunswick are employed in the primary sector of industry. More than 13,000 New Brunswickers work in agriculture, shipping products worth over $1 billion, half of which is from crops, and half of that from potatoes, mostly in the Saint John River valley. McCain Foods is one of the world's largest manufacturers of frozen potato products. Other products include apples, cranberries, and maple syrup. New Brunswick was in 2015 the biggest producer of wild blueberries in Canada. The value of the livestock sector is about a quarter of a billion dollars, nearly half of which is dairy. Other sectors include poultry, fur, and goats, sheep, and pigs.

About 83% of New Brunswick is forested. Historically important, it accounted for more than 80% of exports in the mid-1800s. By the end of the 1800s the industry, and shipbuilding, were declining due to external economic factors. The 1920s saw the development of a pulp and paper industry. In the mid-1960s, forestry practices changed from the controlled harvests of a commodity to the cultivation of the forests. The industry employs nearly 12,000, generating revenues around $437 million.
Mining was historically unimportant in the province, but has grown since the 1950s. The province's GDP from the Mining and Quarrying industry in 2015 was $299.5 million. Mines in New Brunswick produce lead, zinc, copper, and potash.
