Effective Site Safety
Made in NZ for NZ



One of the key considerations in the design of d_Fence has been to develop a product that meets all relevant health and safety, and legislative requirements. Please use the links below to check the current Transit New Zealand regulations for the construction and use of safety fences and barricades. Building codes for swimming pool fencing is also included.

In 2012 dFence requested a letter of compliance for dfence from the NZTA. This was supplied once an attachment point at both the upper and lower levels was included. D-Fence is supplied with clips linking panels together at both the lower and upper points of the fence panel. The bottom clip is placed around the panel like a circlip linking the panels at the lower level. The clips have enough movement in them to work on undulating ground as well as on flat ground.

LEGISLATIONS - Section B6 - Safety Fences

Safety Fences

Safety fences are required to prevent people from gaining access into a hazardous area. This is particularly important at unattended worksites.


Fences shall:

  • Have a secure top and bottom rail
  • Have a top rail located a minimum of 1.0m above ground level
  • Have the bottom located a maximum of 100mm off the ground
  • Be continuous around the hazard
  • Be clipped together, if in sections to form a continuous fence surrounding the hazard
  • Have top and bottom rails which terminate with a vertical rail
  • Have a child proof infill or solid panels which are difficult to climb and are fluorescent orange version 4
  • Remain up right and stable under all expected site conditions
  • Be free from sharp objects

Night use

Yellow flashing warning lamps must be placed on safety fences and barricades when they are used to protect a hazard less than 30 metres long on level 1 roads. A lamp must be placed on at least each corner of the safety fences to make the hazard more identifiable.

On all levels of road the delineation of hazards parallel to the direction of the traffic and more than 30 metres long shall be by safety fence s or barricades fitted with suitable reflectorised delineators.

The Code of Practice recommends the use of 200mmx150m Retro-Reflective Chevron delineators.

These should be installed at ten metre spacing and at every change of direction of the safety fence or barricade.

Plastic Water filled Barriers (new in August 2012)

Plastic water filled barriers that do not conform to the requirements of NZTA M23:2009 must not be used as barriers

However plastics water filled barriers may be used as a safety fence under the following conditions

The design and installation must comply with the design requirements of safety fences above

Must be separated from the live lane by a minimum of 1m lateral safety zone and a row of traffic cones at appropriate spacings

Must only be used in a speed zone of less than 65km/hr

Section B7 – Barricades (read more)

LEGISLATIONS - Section B7 - Barricades

Barricades shall only be used for delineation of a hazard behind a line of delineation devices. Barricades may also be used to physically close roads.

Barricades shall be lightweight, frangible and constructed from non-splintering plastic material. When in place on site the barricade, consisting of legs and a sight rail, must be joined together to form a one-piece unit.

Hurdles are NOT a recommended temporary traffic management device and the code of practice discourages their use. Cones or barricades can usually be used instead of hurdles.


Barricades shall:

  • have sight boards with a vertical dimension of 150mm to 300mm and horizontal lengths of 600m to 1800mm, and
  • the sight board shall be mounted with the centre line of the uppermost rail 900mm, +/- a 120mm tolerance, above the ground surface.


Barricades must be:

  • a fluoroescent orange colour that conforms to the CIE chromaticity co-ordinates in table 2.1 of the joint Australian & New Zealand Standard AS/NZS 1906.4:1997, and
  • conform to the minimum luminance factors specified with table 2.2 of the joint Australian and New Zealand Standard AS/NZS 1906.4:1997.

Barricade sight boards must have alternating 100mm wide white and fluorescent orange stripes that slope at 45 degrees to the vertical, with the lowest point of the strip toward the live lane. The stripes shall be class 1 retro-reflective material and shall be applied to the full length of the sight board.
