City Rail Link


CKL has been engaged by Auckland Transport to prepare the strata legalisation plans for the acquisition of a subterranean corridor for the construction of Auckland’s City Rail Link (CRL). The CRL will comprise twin 7.5m diameter tunnels over a distance of 3.4km.

As part of the CRL project team, CKL has provided initial input for the notice of requirement plans and has completed the first set of tunnel survey plans.
CKL has undertaken extensive site surveys, including basement levels of structures above the proposed tunnel, to ensure clearances are achieved and minimal effects on the property owners above.

The development of the CRL will require amendments to the titles of many of the existing private properties above the proposed tunnel. Title amendments will represent the limit of their rights below the surface. These will need to be recorded on legalisation plans, which will be prepared and submitted by CKL for the review and approval of the Chief Surveyor at Land Information NZ.
