     I was under the impression that the Sahiwal/Friesian cross was 
     originally bred in Australia (why did they breed them in NZ ? I 
     wouldn't have thought of NZ as having any tropical areas, but then 
     I've never been there). No mention of the NZ version on the site, 
     perhaps an oversight that warrants correction.
     
     I found the following information at 
     http://www.ansi.okstate.edu/breeds/cattle/
     a very comprehensive site on breeds of livestock
     
     Australian Friesian Sahiwal
     
     This breed is being developed in Australia by the Queensland 
     Government for use in the tropical areas.
     The breed was evolved using the Sahiwal, a dairy strain of Zebu 
     from Pakistan, and the Australian Holstein-Friesian.
     
     Since the 1960's when research work began on this breed, notable 
     progress has been achieved towards the objective of combining tick 
     resistance and heat tolerance with reliable milk production and 
     fertility. It has now been extensively tested in the tropical and 
     sub-tropical areas of Australia. Under these conditions, it 
     outperforms the Holstein Friesian by approximately 15 percent.
     
     Average milk yield is 3,000 litres for mature cows. Milk quality 
     is good - protein level is 3.4 percent and butterfat is approximately 
     four percent.
     Limited numbers are available for export, however, semen is 
     readily available.

     ====================================================
     The same site has a listing for the Gir (although not the Brazilian Gir)
     
     Gir
          The Gir is one of the principal Zebu or Bos indicus breeds in India 
     and is used for both diary and beef production. It has been used locally in 
     the improvement of other breeds including the Red Sindhi and the Sahiwal. 
     It was also one of the breeds used in the development of the Brahman breed 
     in North America. 
     
          The Gir is distinctive in appearance, typically having a rounded and 
     domed forehead, long pendulous ears and horns which sweep back and spiral 
     up. Gir are generally mottled with the color ranging from red to white. 
     They originated in southwest India in the state of Gujerat and have since 
     spread to neighboring Maharashtra and Rajasthan.
     
          The females average 385 kg with a height of 130 cm and the males 
     average 545 kg and a height of 135 cm. The average milk production for the 
     Gir is 1590 kg per lactation, with a record production of 3182 kg at 4.5% 
     fat.
