All of the above is subject to consultation/price negotiations with the airlines. If the airlines don't want to pay CAPEX generally doesn't happen without a direct business case.
Unless, if our government or a foreign government mandate changes to the security rules then that money must be spent on upgrading equipment and/or space without consultation or price negotiations. Or such negotiations are “from X date we are mandated to do this, it will cost this, if you don’t like it then stop operating from here.”
If you’ve travelled domestically on a jet out of Auckland, there is considerable expense being made by Auckland airport in the domestic terminal due to the updated security rules which require domestic passengers to be screened with body scanners.
Other airports have the space able to do start installing or using the scanners now, however Auckland didn’t have the space to do so. They were originally due to be used from early 2021, but were delayed due to covid.
