Livestock numbers drop from 2017 to 2018
In 2018, there were 38.3 million livestock in New Zealand, including sheep, dairy cattle, beef cattle and deer (Table 1). Compared to 2017, the total number of livestock decreased by about 0.7 percent (almost 250,000 animals).
Table 1: Number of livestock, by type, 2017-2018
From 2002 to 2018, the total number of livestock decreased by 25 percent, from 50.9 million to 38.3 million. The number of sheep decreased from 39.6 million in 2002 to 27.3 million in 2018, a decrease by one third. In contrast, the number of dairy cattle increased by almost a quarter, from 5.2 million in 2002 to 6.4 million in 2018 (Figure 1).

Increase in dairy cattle numbers in many regions
Dairy cattle farming can have negative effects on water supply levels as well as water quality.
Between 2007 and 2017, the number of dairy cattle increased substantially, especially in the South Island in Canterbury (73.3 percent), Southland (57.4 percent) and Otago (53 percent) (Figure 2). In the North Island, the regions with the largest increase were Gisborne (19.2 percent), Manawatu-Wanganui (17.7 percent) and Waikato (12.1 percent).

Livestock density by territorial authority
Livestock density gives an indication of the number of livestock per total land area. The measure does not account for the amount of agricultural land, so should be interpreted with caution.
In 2017, New Zealand had an average livestock density of 144.4 animals per square kilometre (Figure 3). Sheep were the predominant livestock type - with an average density of 103.0 animals per square kilometre.
In 2017, Gore District had the highest density of livestock (684.5 animals per square kilometre), followed by Central Hawke's Bay District (391.3 animals per square kilometre) and Masterton District (390.6 animals per square kilometre).

Matamata-Piako District (211.1 dairy cattle per square kilometre), Waipa District (183.4 dairy cattle per square kilometre) and Hauraki District (118.0 dairy cattle per square kilometre) were the Territorial Authorities with the highest density of dairy cattle in 2017.
