Maungaraki Cattle Company




Maungaraki is located in the limestone ranges south east of Masterton in Wairarapa province in the southern part of the North Island and is approximately 100 kilometres north of Wellington International Airport.

The cattle studs are run on approximately 80 hectares of medium hill country where the winters are long and cool with several snow falls annually. It is traditionally summer dry country but is highly fertile and with the limestone base it is ideally suited to running healthy breeding stock.

The annual rain fall is around 1200 mm or 44 inches. December through to March is normally the drier months.

Hay and barley straw are fed out in the winter months to supplement in the shortage of grass.

Bulls are usually wintered on green feed crops and if necessary supplemented with balage. No grain or hard feed are fed to sale bulls.

The company was set up after the purchase of Maungaraki farm in 1987 with the aim of producing quality seed stock for the stud and commercial beef breeding industry in New Zealandand overseas.

Over 100 registered breeding females calve annually. They are run under commercial conditions on hill country running up to 1700 feet asl.

Heifers are expected to calve as 2 year olds.

All calves are weighed at birth and fully performance recorded on Breed Plan. Fat depth, EMA and IMF data is recorded at around 15 months on all bulls and they are service and semen quality tested prior to sale. Yearling bulls and replacement heifers are all structurally assessed using the Beef Class system.
