workers repaired sections of the roof and walls at titikaveka cicc church this week on rarotonga, hoisting in concrete by crane. a day or so later, heritage observers were disturbed to see the church's wooden window frames ripped out. other churches around the country have most commonly replaced historic frames with modern aluminium ones. this leaves an ever dwindling number of churches in their original state. so far, critics say a historic places board has been completely ineffective in protecting the many heritage sites around the country.
