REF: OIA-11517 
 
Dear Richard 
 
Request made under the Official Information Act 1982 
 
Thank you for your email of 17 November 2022 requesting the fol owing information under the Official 
Information Act 1982 (the Act) in relation to the reply that you received to OIA-10818: 
 
Thank you for this material - much of which is newly released. Having read the provided 
information I cannot see any evidence of anything pre-dating mid 2022 which relates to the 
17,000vpd figure which Waka Kotahi relied on in the Nov 2021 document (08). 
 
I do note however that drafts of 'Cycle Lane Traffic Assessment' across June 2021 progressively 
removed text and data likely to be supportive of a Cycle Lane (Shared Path) and the inclusion of 
material not supportive of capacity for a cycle lane. I therefore invite Waka Kotahi to provide an 
explanation for these redrafts. 
 
Additionally, in Document 12 (Page 2) your Graham O-Connell (11/7/22 11:05am) asks the ASM 
to 'write a mythology' on the source of 17,000vpd for use in responding to the OIA. The ASM 
agree to do this (11:10am) but caveat their reply (6:05pm) that the 17,000vpd figure they produce 
is a 'a coincidence' as they were unaware of it in 2021 other than seeing it in the media. 
 
This email trail was circulated to senior staff in Waka Kotahi, ASM and Resolve none of whom 
appeared to flag concerns that there was clear evidence that the OIA reply relating to the 
17,000vpd (Nov 2021) was back-calculated in 2022 to best match the November 2021 figure 
(ASM call it 'a coincidence') and that a 'mythology' (a fictional work) was written to lend credence 
to it. 

 
The basis for the figure of 17,000 vehicles per day can be found on pages 26 (Table 4, Level 4 
information) and 28 (level 4 demand reduction graph) of the Auckland Harbour Bridge Active Mode 
Provision – Traffic Impact Assessment (24 June 2021)
. This report was provided to you as Attachment 
6 in the Waka Kotahi response to OIA-10818. The explanation for this figure is also outlined in the 
Resolve email of Wednesday 20 July 2022, at 3:27 PM (the first email in Attachment 12 provided to 
you in response to OIA-10818).  
 
 
  


Your remaining questions require Waka Kotahi to form an opinion or provide an explanation, and so 
create new information to answer the request. Waka Kotahi is not under an obligation to create new 
information in order to response to a request.  
 
If you would like to discuss this reply with Waka Kotahi, please contact Ministerial Services by email to 
[NZTA request email].  
 
 
Yours sincerely
