She said the ministry immediately responded and local Conservation Department operations ranger Karl McCarthy was on the case within hours.
"When Karl arrived he used his mobile phone to call out to the bird which flew down from the tree and landed on the powerlines. He then called out to it again and as it came closer he shot it."
Mrs West said it was all over within 15 minutes.
"It's a beautiful-looking bird. It's a shame that it's such a destructive little bird which poses a huge threat to our kiwifruit industry."
Mrs West said if the bird had been allowed to live and breed, it could have been devastating for the agriculture and kiwifruit industries.
"It's the last thing we need," she said.
Mrs West said unlike some other birds, the red-vented bulbul breeds all year round.
Red-vented bulbuls are known to cause significant damage to fruit and vegetable crops and aggressively chase and attack other birds.
It feeds on native fruits, berries, insects, flower nectar, seeds and buds.
Mr McCarthy said the Red-vented bulbul was one of the top 100 invasive organisms in the world.
"It's a huge concern to have not only have reports of possible sightings but find a live bird.
"Pat and Don did a really excellent job in reporting this sighting straight away." Mr McCarthy said that, previously, the Ministry of Primary Industries had offered a $1000 reward for information leading to the capture of this pest and the Wests may be up for a reward.
