Dear Mr Ross
Local Government Official Information and Meetings Act 1987
Thank you for contacting Auckland Transport (AT) on 25 August 2016 requesting the following
information in relation to mass transit options to the airport.
All of the information you have requested is available in the report from the South-western Multi-
modal Airport Rapid Transit Draft Indicative Business Case (IBC), which can be found at the link to
the AT website (Link 1). AT is currently investigating mass rapid transit options to the airport, with light
rail and bus being looked at as options. Additional information about the decision made by the AT
board to discount heavy rail to the airport can be found in the SMART board report (Link 2).
Your request has been emphasised in bold as follows:
1) Benefit Cost Ratios and analysis for Light Rail to the Airport
These can be found from page 113 of the IBC (Link 1).
2) Benefit Cost Ratios and analysis for Heavy Rail from Onehunga to the Airport via Mangere
3) All information and analysis to date on heavy rail from Otahuhu to the Airport via Mangere
The long list options for heavy rail can be found on pages 49-53 of the IBC and the short list options
for heavy rail can be found on pages 66-71 (Link 1).
3a) Any initial costs of construction and land acquisition if this option were to proceed
Cost estimates can be found in Appendix F of the IBC entitled Shortlist Option Estimates at the
website link (Link 1).
3b) Estimated time of construction
Detail about timing can be found on page 118 of the IBC (Link 1). The timing was based on a guiding
assumption in order to calculate the costings of the project and is being worked through as part of the
Auckland Transport Alignment Project which will confirm the timing of investment in mass rapid
transit. Please see Link 3 for more information on ATAP.
3c) Suggestive operation patterns and frequencies servicing this line
Information about operation patterns and frequencies is included in the assumptions list for the long
list option identification and evaluation on page 49 of the IBC (Link 1).
3d) Why was this option dismissed out of hand early on rather than given full analysis like
options 1 and 2 despite having a better benefit cost ratio as suggested here:
The option was not dismissed but assessed against same criteria as other corridors and came fourth.
The top three corridors were progressed further.
Top 3 corridors:
Northern and southern loop
Please see sections 4.4.7 on page 40; 5.3.3. on page 51; 5.6.4 on page 65; 5.11 on page 73 of Link 4.

We trust the above information has addressed the matters raised however, should you believe that
we have not responded appropriately to your request, you have the right in accordance with section
27(3) of the LGOIMA to make a complaint to the Office of the Ombudsman to seek an investigation
and review in regard to this matter.
