6.  Any and all memos formal & informal, email, correspondence, input involved, reports and 
recommendations associated with the closure of the Marsden Refinery specifically 
associated with Bitumen - correspondence to include National Security, Costs for 
Bitumen, correspondence with the Minister - I am specifically after all the input associated 
with Bitumen and the Marsden refinery 

 
On 26 October 2022, we contacted you to seek clarification of what timeframe your request for 
correspondence and documents covers, we also invited you to specify the particular documents you 
seek, since as it stands, this part of your request is not specified with due particularity as required 
under section 12(2) of the Act.  
 
As we have not received a response from you, we are unable to answer this part of your request. 
 
Waka Kotahi has received Official Information Requests for specific documents and correspondence 
relating to bitumen previously. We have published a response, and the documents that fell within 
 
 



 
scope of the request, on our website. You can find this under the New Zealand bitumen supply 
response from 8 April 2022 on our website at: 
www.nzta.govt.nz/about-us/official-information-act/media-official-information-act-oia-responses/.  
 
7.  If the Transport Agency did not have input please let me know why 
 
While Waka Kotahi holds correspondence and documents regarding bitumen, we were not directly 
involved in discussions about the Marsden Point Oil Refinery being closed down. 
 
8.  Costs of bitumen from 2016 and onwards per month that the Transport Agency paid up 
until todays date 
 
Waka Kotahi does not pay for bitumen directly. Bitumen, used on Waka Kotahi works projects, is 
purchased by the contractor that Waka Kotahi has employed for a project or by a sub-contractor. The 
cost to supply, for example, a square metre of chip seal or asphalt surfacing, is commonly known, but 
the cost of the individual materials required to deliver it, such as bitumen, is not. 
 
While Waka Kotahi does not know what its contractors pay for bitumen, the monthly Z Energy bitumen 
list price per tonne is supplied to Waka Kotahi by Z Energy to allow us to calculate our ‘bitumen cost 
adjustment series’. The Z Energy list price is commercially sensitive due to Z Energy being in a 
competitive market, we are therefore withholding this cost of bitumen under section 9(2)(b)(ii) of the 
Act to protect information where making it available would be likely to unreasonably to prejudice the 
commercial position of the person who supplied or who is the subject of the information. 
 
With respect to the information that has been withheld, I do not consider there are any other factors 
which would render it desirable, in the public interest, to make the information available. 
 
9.  Please provide the date Marsden refinery 
 

When we contacted you on 26 October 2022, to seek clarification of your request, we also asked that 
you clarify this question as it appears the sentence is not complete. As we did not receive a response 
from you, we are unable to answer this part of your request. 
 
Under section 28 of the Act, you have the right to ask the Ombudsman to review my decision to 
withhold certain information. The contact details for the Ombudsman can be located at 
www.ombudsman.parliament.nz. 
 
If you would like to discuss this reply with Waka Kotahi, please contact Ministerial Services, by email 
to [NZTA request email]. 
 
 
Yours sincerely
