"Heavy maintenance'' will be used to rebuild the Severn St wall at the southern end of Oamaru.
The 80-year-old, three-tiered landmark entrance to the Waitaki town failed in May 2016, months after the Waitaki District Council spent $45,000 improving its stability, removing leaning sections, re-establishing drainage, and building a new stone wall.
After more than three years - and estimates for a rebuild that swelled to $1.3million - the council this week unanimously approved rehabilitation of the wall for $550,000, including a NZ Transport Agency subsidy, which fitted established budgets.
The reconstruction, recommended by Oamaru stone masonry firm Dooleys Masonry, followed a Stantec report that said only 33% of 350m of the two failed walls required heavy maintenance.
A survey conducted by the council in May showed more than half of the 156 respondents wanted a full replacement of two tiers of walls with Oamaru stone facing, which was estimated to have cost $1.3million.
Council reports said the work would meet ``the tests of aesthetics, engineering solutions and affordability''.
