The Auckland Rail Network Rebuild project comprises the upgrade of the Auckland rail network in preparation for the opening of the City Rail Link (CRL) which is expected to be completed by the end of 2024.
The scope of work includes:
- removing the rail lines, sleepers and turnouts
- digging out the existing formation and ballast
- installing a new formation
- installing a new ballast
- installing new drainage formation to prevent future deterioration, and

- Eastern Line (Stage 2)
- Western Line (Stage 3a)
- Southern Line - Papakura to Puhinui (Stage 3b)
- Southern Line - Pukekohe to Papakura
- Southern Line - Puhinui to Otahuhu
