TWO vials, which the owner claims contain the spirits of ghosts exorcised from a house in New Zealand, have been put up for sale on online auction site, TradeMe.

So far, bidding on "Two Captured Ghosts" had reached $NZ410 ($A316), and incited hundreds of comments, with advice ranging from how to get rid of the spirits for good, to the ethics of selling someone else's captured immortal essence.

Before the exorcism, the seller said he and his partner were plagued by noises, strange "vibes" and the mysterious flicking of switches. After contacting spiritualist churches, they were referred to an exorcist, who put the ghosts in the bottles.

Since having their troublesome housemates removed last July, the couple had experienced no further disruptions, he said.

The auction description claims the spirits were captured by an exorcist from a spiritual church at a property in Christchurch, the largest city on New Zealand's South Island.

The seller claims that one spirit belongs to a man who died in the house in the 1920s.

"We have had no (paranormal) activity since they were bottled on July 15, 2009," the seller said.

"So I believe they are in the bottles."

The auction said the "holy water" in the vials dulled the spirit's energy and put them to sleep.

To revive the spirit, the buyer would need to pour the contents into a dish and let it "evaporate into your house''.

"I just want to get rid of them as they scare me,'' the seller said.
