This specification, HM14 Edgebreak, replaces specification TNZ C7 Repair of edge break. However, if TNZ C7 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.
