Tegel won't be prosecuted over footage taken inside one of its farms showing dead and deformed chickens.
Animal advocacy group Direct Animal Action captured the footage during two visits to the poultry giant's farm near Helensville in July, with the hope of bringing Tegel's plans for a mega farm in Northland to a halt.
It found numerous dead chickens, lame chickens struggling to walk, cannibalised chickens, chickens lying on their backs unable to get up and a chicken with a grossly deformed beak that was unable to eat or drink properly.
The footage was reported to the Ministry for Primary Industries, sparking an investigation, including a surprise inspection of the site. That investigation concluded last week, finding no offences were detected against the Animal Welfare Act 1999.
In a statement to the Herald, MPI's Manager of Animal Welfare Compliance, Gray Harrison, said the inspector looked at bird health, mortality rates, removal of dead stock and stocking rates.
