Trust chairman Marcus Brown told the annual meeting last night a full structural assessment of the trust's buildings had been carried out by Hadley and Robinson.
An interim report following initial inspections indicated none of the buildings owned by the trust were at risk from earthquakes.
The buildings were within the Government's 33% threshold, but the trust was waiting for the full report before going in to details.
''Earlier, trustees undertook a number of structural improvements to the [building] portfolio on acquisition,'' he said.
Without that, the present situation could have been much worse.
Last night's annual meeting was a milestone for the trust, 25 years having elapsed since its incorporation.
The trust had continued to grow and had become the leading heritage organisation in Oamaru and the region, and was well-recognised further afield.
''As we maintain our buildings, strive to be good custodians and keep the heritage dream alive in the precinct, we are now also faced with some issues not considered or even known about in 1989,'' Mr Brown said.
The trust was not only commercial property managers, it had a bigger and more complicated role to play.
''We still need to increase the standards of care for some of our buildings, while compiling a complete schedule of works and supporting project plan to ensure that nothing is overlooked.''
This could not be funded from rents alone and the trust had to become more pro-active in finding funding solutions. Outlining the past year, Mr Brown highlighted developments including a trial with Tourism Radio, which used GPS technology to tell tourists about the area they were driving through, its attractions and places of interest.
Survey results from Tourism Radio showed a 60% increase in the number of campervans visiting the precinct in the past year, although the trust would be conducting its own survey to expand the data.
