New Zealand farm structure change and intensification

Abstract

This report presents information about the numbers of farms in New Zealand. The different sources providing such data report very different figures and trends over time, but they all seem to indicate an overall trend of decrease in total farm numbers over the last decades, which appears to be due mainly to a decrease in the numbers of grazing and fattening farms and in the number of arable farms. The distribution of farms by size range over time shows an increase in the proportion of both the smallest and the largest ones, at the expense of the midsized categories. However, different trends can be observed depending on the farm type. The report then explores the change in livestock numbers over time. Thus, during the last 20 years, the main trends consist in an overall decrease in sheep and beef numbers, while dairy and deer numbers increased. To conclude, the report deals with the question of intensification in New Zealand farming systems. It underlines the increase in numbers of cows per hectare and production per cow in the dairy sector, and the increase in lambing rates and carcase weights in the sheep and beef sector. These changes can be linked to the increasing expenditure in agricultural research and development as well as the increasing use of services such as herd testing. Also reported is the growing use of fertilisers in New Zealand agriculture.
