A Taranaki contract milker cut teats off 12 cows by placing rubber rings on them and slicing them off with scissors.
Claudio Da Costa, 47, told Ministry for Primary Industries investigators he cut them off with scissors because it was a 'quick and cheap fix for the problem'.
The Ministry for Primary Industries began an investigation after receiving a complaint to its Animal Welfare hotline in November last year when Da Costa was working as a contract milker at a property in Okato, south of New Plymouth.
MPI's Wellington/Taranaki District Compliance Manager, Mike Green, says the farm's owners found 12 dairy cows to have missing teats and consulted a vet to find out what had happened to them.
