Dear Dianne 
 
Request made under the Official Information Act 1982 
 
Thank you for email of 27 August 2019 to the Minister of Transport, Hon Phil Twyford requesting 
information under the Official Information Act 1982 (the Act). On 29 August 2019, your request was 
transferred to the NZ Transport Agency for response. 
 
On 13 September 2019, the NZ Transport Agency extended the timeframe for responding to your 
request under section 15A of the Act. As advised, we required an additional 15 working days to 
respond to your request. The deadline was extended because your request necessitated a search 
through a large quantity of information and meeting the original timeframe would have unreasonably 
interfered with the Transport Agency’s operations and could not have been made within the original 
20 working day limit. 
 
Your questions are numbered and decisions on each part are provided below: 
1.  March 2000 - Siblair Knight Merz prepared an outline plan report for NZTA on SH58/Flightys 
Rd/Murphys Road intersection - What was the proposed cost to make the proposed 
changes to this intersetion reconstruction? 
This part of your request is refused under 18(e) of the Act. As the March 2000 report was 
produced over 19 years ago, the Transport Agency does not hold an electronic copy of this 
document and despite efforts to locate a hard copy, this document was not found. 
2.  13 November 2014 - the budget was set at $30M to upgrade and implement safety 
improvements on SH58 https://www.nzta.govt.nz/media-releases/30m-proposal-to-make-
sh58-safer/ - what safety improvements did this include? 
The safety improvements included straightening some tight bends, introducing safer speeds to the 
area, installing wire rope safety barrier and building a new roundabout at Moonshine Road. Initial 
work carried out shortly after the 2014 media release addressed the high-risk area north of 
Mt Cecil Road. 
3.  21 November 2014 - "Proposed improvements were to include wire rope barrier" What was 
the specific budget allocation for the Wire Rope Barrier. 
There was no specific budget allocation for the wire rope barrier at that date. Instead, the whole 
project was estimated at $30M to incorporate the proposed improvements. Specific budget 
allocation is subject to tendered and negotiated rates. 
 
4.  28 November 2014 - "work on the western section, currently operating under a reduced 
speed limit, is due to commence in December.  This first-stage work involves straightening 


the road, installing 700m of wire rope safety barrier to protect motorists from head on 
collisions, and improving drainage to maintain the road’s integrity, as the stream has 
washed away its foundations" https://www.nzta.govt.nz/media-releases/transport-agency-
thanks-local-community-for-input-on-sh58-safety-upgrade/ - Why did this work not 
commence? 
There were minor delays in the award and negotiations for the work. The work was awarded in 
December 2014 with the start date delayed beyond the Christmas break and works commencing 
early in 2015. 
5.  16 January 2015 "This realignment is the first stage in a wider $30m package of 
improvements scheduled for SH58 between SH2 and Transmission Gully, which includes 
further curve realignments, a reduction in the speed limit (from 100 to 80km/hr), the 
installation of a wire rope barrier and a roundabout at Moonshine Road", 
https://www.nzta.govt.nz/media-releases/state-highway-58-safety-improvements-to-begin/ - 
When was the $30m package of improvments cancelled? 
The improvements package was not cancelled. The $30M package of improvements has since 
been expanded to include a new roundabout and bridge on Flightys Road, improved pavement to 
allow for increased traffic loading, and to factor in market constraints. 
6.  15 July 2015 "the installation of a wire rope barrier and a roundabout at Moonshine Road", 
https://www.nzta.govt.nz/media-releases/state-highway-58-sealing-works-paused-for-
winter/ - What was the specific cost for the roundabout at Moonshine Road? 
There was not a specific cost for the roundabout at Moonshine Rd in July 2015 because the work 
had not been tendered or priced at that time. 
7.  In 2017 (engagement report below) it was detailed the "proposed package" of safety 
improvements for SH58. It is interesting to note that some of the "proposed package" of 
safety improvements were actually carried over from 2014. https://www.nzta.govt.nz/assets 
/projects/sh58-improvements/SH58-engagement-report-Sept-2017.pdf 
The 2014 package of improvements referred to a section of road between Mt Cecil Road and 
Harris Road. These works were completed prior to the 2017 report which proposed safety 
improvements for the remainder of the route from Haywards Interchanges to Bradey Road. 
8.  18 July 2017 "Package of saftey improvements", https://www.nzta.govt.nz/media-
releases/package-of-safety-improvements-proposed-for-sh58-haywards/  
a)  What was the difference between the safety improvements as outlined between 
November 2014 - July 2015? 
The additional safety improvements announced in July 2015 that were not announced in 
November 2014 included a new roundabout at the Murphys/Flightys intersection, widening the 
shoulders and bridges, and installing side barriers. 
b)  What was the specific cost for the Round about at the intersection of 
SH58/Flightys/Murphys Road in July 2017? 
There was not a specific cost for the roundabout at the intersection of SH58/Flightys/Murphys 
Road in July 2017 because the work had not been tendered or priced at that time. 
 
c)  What was the specific cost for the Round about at the intersection of Moonshine 
Road/SH58 in July 2017? 
 



There was not a specific cost for the roundabout at the intersection of Moonshine Road/SH58 
in July 2017 because the work had not been tendered or priced at that time. 
9.  20 March 2018 "“SH58 has accumulated one of the worst safety records in New Zealand 
and it’s a priority for the Agency to make significant safety improvements as soon as 
possible" https://www.nzta.govt.nz/media-releases/transport-agency-proposes-safety-
improvements-for-sh58/ - Specifically What significant safety improvements was NZTA 
referring to in this release? 
This media release referred specifically to “a lower speed limit, along with other improvements like 
straightening dangerous curves, intersection improvements and installing a median barrier”.
