# FarmClass

Description:
Located mainly in Marlborough, Canterbury and Otago.  Extensive run country located at high altitude carrying fine wool sheep, with wool as the main source of revenue.


Description:
Mainly in Canterbury.  Mainly fine wool sheep with a carrying capacity of around four stock units per hectare.  Wool and  sales of cast-for-age ewes are a major source of revenue.


Description:
Mainly located on east and west coasts and the central plateau of the North Island.  Carrying eight to nine stock units per hectare with eight sheep per cattle beast. Sheep provide around 65% of the revenue.


Description:
Located throughout the NI.  Easier hill country and smaller holdings than Class3.  Mainly Romney sheep and carrying around 11 stock units per hectare with 7 sheep per cattle.  A high proportion of sale stock sold is in forward store or prime condition.


Description:
Mainly located in South Auckland, West Coast North Island and Hawkes Bay.  High producing grassland farms carrying twelve stock units per hectare with six sheep per cattle beast.  Replacement ewes are often bought in.


Description:
Mainly in Canterbury and Otago. A more extensive type of finishing farm generally breeding its own replacements and frequently with some cash cropping.


Description:
Mainly in Southland, South and West Otago.High producing grassland farms carrying about twelve stock units perhectare and with some cash crop.


Description:
Mainly in Canterbury with high proportion of the revenue being derived from grain and small seeds as well as finishing stock.
