A Whakatu company has signed a deal to supply Singapore Airlines with sausage casings.
Luke Kavanagh and Ron Robbie established NZCC three years ago and the company currently processes 300km of sheep intestines a day.
The casings are exported to sausage manufacturers and specialty butchers overseas because New Zealanders prefer larger sausages, which usually use artificial collagen cases.
The larger New Zealand sausage makers were clients but 95 per cent of casings were exported, Mr Kavanagh said.
"Natural sheep casings are more suited to traditional breakfast sausages, which are predominately consumed by Europeans."
Like many New Zealand exporters of primary produce the focus is shifting to Asia. As well as the agreement to supply Singapore Airlines' sausage manufacturer, NZCC recently extended a contract with one of Japan's largest sausage makers.
