Frequently Asked Questions
We will need to know several details about the site and conditions to provide an estimate. All work is charged on an hourly basis.
Pathfinder is available Monday - Friday, Weekends and Public Holidays. Call out | Emergency work is available after 5.00pm and before 7.00am
Yes we can locate telecom both copper and fibre optic services.
No provided prior arrangement with property owner or site contractor has been made and access to property is available.
There are many things to consider that may vary the time.
  • Number of services to locate.
  • Availability to service access points.
  • Terrain to traverse while locating services.
  • Interference from nearby services or infrastructure.
The locator maybe able to give an approximate time given prestart conversation, images or inspection.
If you have any plans available even hand sketches these will be very helpful to the locator. Most utility providers can supply plans up to the property boundary but not usually within the property.
Not unless specifically asked for. These services are available via third party qualified practitioners and will incur additional charges. Pathfinder only paints the ground to indicate their location.
Email pathfinder@inspire.net.nz with your contact details, preferrably an email address for billing, a site address or location, where possible a Google Maps screenshot or complete the Enquiry Form .
  • All utilities can be marked up by Pathfinder.

The Ground Penetrating Radar used for locating is designed for utility scanning. It has successfully located services at 2.5m. However site subterrain conditions do affect the Ground Penetrating Radars ability.
The Ground Penetrating Radar may detect waterpipes in the right conditions. The GPR does not detect any specific objects or items. The GPR data is processed and displayed as a radar-gram depicting the change in signal velocity. The locator must interpret the Ground Penetrating Radar images.
Pathfinder has a Damage Prevention And Awareness Policy. Referencing documents outline industry practices for checking EMF distortion and triangulation applications to determine actual conductor location.
Predominantly the Lower and Central North Island. We will travel further provided travel and accommodation are considered.
Have the proposed trench alignment or excavation site marked out by the customer. This will significantly reduce time. All Utility searches and scanning will be reduced to the marked area. The alternative option where Pathfinder find all the services in a given area then the customers decides the alignment based on the findings is a far longer process.
If the cable is in good condition with no interferring energised sources nearby and a good access point. Then it's possible to trace up to 2km
When locating underground utilities, the locator may occasionally designate a utility to an unknown termination point. The locator will label this as EOI (End of Information) with paint on the ground. This term EOI accurately describes the situation. EOI's are not all that uncommon. Broken tracer cable on gas systems, and sections of plastic pipe in a primarily ductile pipe system will all produce EOIs. Additionally, drastic changes in elevation or utility depth can also produce EOI points.
Pathfinder locators are not certified by BeforeUDig. We are happy to provide work referees and information regarding;
  • Insurance.
  • Standard Operating Procedures.
  • Damage Prevention & Awareness Policy.
  • Personnel locator training.
Notify the utility provider. Take photographs and if required follow up with your incident reporting. Even if Pathfinder locators are onsite they cannot repair any damaged utilities. Please read the Terms And Conditions Of Underground Utility Locating.
Pathfinder will paint a 500mm extent window on a difficult locate or where the locate has been triangulated. Otherwise a spot or cross to indicate the utilities position and directional lines either side to indicate direction.
No, a locator with the specific marker ball or EMS marker application can only be used.
No, the marker balls are activated by the hand held locator. Normally the hand held locator can trigger and detect a marker ball upto 1.5m in any direction.
A service clearance would limit the search & scan area to a specific alignment or small designated area. For example a trench line or vertical drill site. A service locate might refer to a specific service ie: just find the power. Alternatively it means all services are located within a wider area. There are some minor procedures Pathfinder does differently depending on the type of service request.
