Yesterday Ms Scott, who has led a campaign to the Environment Court to preserve the Italian marble altar in the chapel, looked through the building to see what chattels had been removed.
When the property was sold in 2000 to Japanese businessman Dr Hirotomo Ochi, ownership of the chattels, including the ornate altar, was retained by the Dominican Sisters, who ran the school.
Dr Ochi died in 2005.
While removal of the altar is awaiting an Environment Court hearing, other items have been removed, some for the Holy Name Church in Dunedin and others for churches in Otago.
Fr Mark Chamberlain, of Holy Name Parish, could not be contacted last night for comment.
Ms Scott was upset yesterday at the removal of the items, which she said had been gifted to the chapel by families associated with the school.
They included a marble stand given by her family, the McCarthys, who originally gave the property for the school.
Among other items removed were four carved rimu choir stalls, put in when the chapel was built, statues of Mary, St Dominic and St Joseph and three marble stands, including one with an angel holding a lamp, which surrounded the altar, she said.
She said the most valuable historically were the choir stalls, which were "beautifully carved".
She also feared there was a move to remove the five stained-glass windows behind the altar.The Dominican Sisters retained ownership of the chattels because they feared they might not be cared for, or be vandalised.
A Herbert couple, John and Joy Murdoch, bought the property recently.
They will take possession on June 1.
Ms Scott believed that what-ever items could be removed had been taken before the new owners took possession.
"I can't understand the motivation behind it [removing the items] when the buyers are local people who will care for the chapel. I can't understand scattering them throughout North Otago," she said.
"The original reason to protect the items is not needed with the new owners." Ms Scott intends to raise the issue as part of the Environment Court hearing on the altar.
