This paper is an edited version of a decision by the Planning Tribunal concerning alterations to a building now known to be situated directly on the Wellington Fault. The Tribunal considered the requirements of the relevant zoning in the Wellington City district planning scheme and heard evidence from a number of people, including two structural engineers and a geologist. While the engineering evidence was in conflict, the geological evidence about the Wellington Fault is of general interest and is included here for the benefit of the wider readership.
