I understand this has occurred at AKL and I note there were a couple of safety related events during the time
any works at a major airport involving displaced threshold would be conducted under a comprehensive MOWP which all operators would have been consulted on prior to issue.
Can you elaborate on what specifically the safety issues were?
if work lights are distracting from seeing the PAPIs or other lights, the TWR should be told and the WSO made to rectify
