"Contraband of all sorts, drugs in particular, are very dangerous in a prison environment," Mr Massingham said.
"As prisoners find new ways of smuggling contraband, we find new ways to detect it. We carry out regular searches every day - on cells, mail, vehicles, visitors, the prison perimeter and prisoners themselves. Searches include those carried out by staff and the use of detection dog teams and electronic equipment."
The recent incident followed another in which a prison officer on perimeter duty with a dog discovered a car in an orchard adjacent to the prison near Hastings on July 28.
According to a summary of the facts, the officer called for police back-up as he blocked the vehicle's exit.
He was challenged by four people in the vehicle, who included Kaka, and a search uncovered 2.5g of methamphetamine, cannabis, tobacco and nicotine patches, packaged to indicate they were about to be thrown over the fence.
Kaka pleaded guilty to charges of possessing methamphetamine for supply, possessing cannabis, being unlawfully in an enclosed yard, and breaching the Corrections Act.
Judge Rea said the prison sentence was less than two years but it was an inappropriate case for the consideration of home detention.
"Introducing drugs to prison is never going to lead to a sentence of home detention," he warned.
