Preline Checklist for Interior Linings NZ

A proven quality control process before installing GIB and interior linings, helping ensure every project is ready for the next stage.

What is a Preline Checklist?

A preline checklist is a quality control process completed before interior wall and ceiling linings are installed. At this stage, services, framing, insulation, fixing requirements, and wet area preparation all need to be checked before the walls and ceilings are closed up.

A thorough preline process helps reduce rework, improve coordination between trades, and maintain build quality from the start.
