Tēnā koe David,  
 
Request for Information under the Local Government Official Information and 
Meetings Act 1987 (the Act) (the LGOIMA) 
 
Thank you for your email of 20 March 2026 regarding the Commercial Vehicle Safety 
Centre  (CVSC),  currently  under  construction  on  State  Highway  59,  Mackay’s 
Crossing. You have requested the following information: 
 
1.  Firefighting Water Supply (SNZ PAS 4509:2008) 
 
The Commercial Vehicle Safety Centre has a heavy vehicle inspection shed 
with an approximate floor area of 260m2 and ceiling height of 5.35 meters, 
which, at present, does not have a fire suppression sprinkler system. Daily, 
the Commercial Vehicle Safety Centre will have heavy vehicles carrying 
hazardous goods on-site. Based only on the inspection shed size and 
height, applying the Firefighting Water Supply (SNZ PAS 4509:2008) Code, it 
dictates a minimum firefighting water supply classification of FW4. This 
classification requires specific minimum flow rates and firefighting water 
provisions.  
 
Please provide the following information regarding compliance with an 
"Acceptable Solution" as mandated by Section 17 of the Building Act 2004: 

 
1a.  The Fire Hazard Category (FHC) calculation and any Risk Assessment 
conducted under Appendix H of SNZ PAS 4509:2008 used to determine 
the water supply requirements. 

This standard is no longer referenced in the Building Regulations and was not 
considered as part of the building consent assessment for the construction of 
the  inspection  shed.  This  part  of  your  request  is  therefore  refused  under 
section 17(e) of the Act as the documents alleged to contain the information 
requested does not exist, or despite reasonable efforts to locate them, they 
cannot be found.   
 
Please note that any information provided in response to your request may be published on the Council website, with 
your personal details removed. 
 

 
1b.  Documentation showing how the total fire load was calculated. 
Specifically, does this calculation account for the "worst-case" 
scenario of peak-hour throughput (e.g., up to 11 heavy vehicles, 
potentially carrying Class 3 or Class 8 hazardous substances) on-site 
simultaneously, or only the physical structure? 

Attached  is  the  fire  report  supplied  for  the  construction  of  the  vehicle 
inspection shed. The report’s analysis is based on a single truck being located 
within the building at any one time.     
 
1c.  Evidence of compliance with SNZ PAS 4509:2008 Table 2 (Method for 
determining firefighting water supply, Note 6 - Alternative Supply), 
justifying why an alternative or on-site water supply was apparently 
deemed unnecessary despite the site’s specific operational risks. 

This standard is no longer referenced in the Building Regulations and was not 
considered as part of the building consent assessment for the construction of 
the  inspection  shed.  This  part  of  your  request  is  therefore  refused  under 
section 17(e) of the Act as the documents alleged to contain the information 
requested does not exist, or despite reasonable efforts to locate them, they 
cannot be found.   
 
1d.  The Fire Engineering Report (FER) or Fire Hazard Category (FHC) 
assessment (as per SNZ PAS 4509:2008 Appendix H) used to justify 
the omission of on-site fire hydrants and/or static water storage. 

Officers  advised  the  fire  report  focuses  on  the  requirements  of  Acceptable 
Solution CAS2.  
 
1e.  Any Fire Design Summary provided to the Kapiti Coast District Council 
Building Consent Authority that outlines how the "Acceptable 
Solution" for fire fighting water is achieved. Please specifically 
address compliance with SNZ PAS 4509:2008 Table 1 (Required water 
supply for firefighting) and SNZ PAS 4509:2008 Table 2 (Water supply 
requirements for fire hazards) given the 960m distance of the 150mm 
main from the source. 

Refer to attached building consent file.  
 
1f.  The results of any physical flow and pressure tests conducted as per 
SNZ PAS 4509:2008 Appendix G (Testing of Fire Hydrants) for the 
150mm water main at the hydrant located near the site entrance. 

This standard is no longer referenced in the Building Regulations and was not 
considered as part of the building consent assessment for the construction of 
the  inspection  shed.  This  part  of  your  request  is  therefore  refused  under 
section 17(e) of the Act as the documents alleged to contain the information 
Please note that any information provided in response to your request may be published on the Council website,  
with your personal details removed. 
 

 
requested does not exist, or despite reasonable efforts to locate them, they 
cannot be found.   
 
 
1g.  The modelled or tested residual pressure at the single hydrant located 
135m from the inspection shed while flowing at the FW4 mandated rate 
of 3,000 L/min (50 L/sec), ensuring compliance with the 100 kPa 
minimum residual pressure requirement, specified in SNZ PAS 
4509:2008 Section 5 (Running (Dynamic) Pressure). 

This standard is no longer referenced in the Building Regulations and was not 
considered as part of the building consent assessment for the construction of 
the  inspection  shed.  This  part  of  your  request  is  therefore  refused  under 
section 17(e) of the Act as the documents alleged to contain the information 
requested does not exist, or despite reasonable efforts to locate them, they 
cannot be found.   
 
1h.  Copies of any correspondence between Kapiti Coast District Council 
Engineering and NZTA (Waka Kotahi) regarding the 135m maximum 
distance requirement between a hydrant and the centre of the main 
entry to the structure, as specified in SNZ PAS 4509:2008 Section L4 
and illustrated in Figure L2(c). 

Please refer to attached emails and correspondence from NZTA.  
 
2.  Access and Safety for Firefighting Operations (Building Code Clause C5) 
2a.  As building work must comply with the New Zealand Building Code 
under Section 17 of the Building Act 2004, please provide information 
regarding compliance with Clause C5: 
 
The building consent file for the construction of the inspection shed is attached 
for your reference.    
 
2b.  Any assessment held by the Building Consent Authority verifying that 
the site layout provides adequate "Access and Safety for Firefighting 
Operations" as required by Performance Requirement C5.2. This would 
include the requirement to safeguarding people from an unacceptable 
risk of injury or illness caused by fire, including the placement of the 
single fire fighting water supply hydrants downwind of the 
predominant wind (North/Northwesterly), unacceptably forcing  
Firefighters to be exposed to toxic fumes. 
 
The building consent file for the construction of the inspection shed is attached 
for your reference.    
 
2c.  Please provide the documentation, such as a Fire Engineering Report, 
or Building Consent Authority assessment explaining how the site 
achieves compliance with Building Code Clause C5.2 and SNZ PAS 

Please note that any information provided in response to your request may be published on the Council website,  
with your personal details removed. 
 

 
4509:2008, specifically addressing how firefighting crews can “operate 
effectively” at a FW4 classified structure requiring 3,000 L/min, while 
relying on a single hydrant located 135 meters away that is capped at a 
maximum design flow of 2,100 L/min (SNZ PAS 4509:2008 - Table 2, 
Note 5)
