This specification, HM15 Service covers, replaces specification TNZ C8 Specification for adjusting service covers. However, if TNZ C8 is referred to in existing contract documents then you may continue to use it. Alternatively you could use MR09 Pre-surfacing repairs if you plan to include all of the following specifications in a single surfacing contract: C4, C5, C6, C7 and C8.
