With the rapid growth of electric vehicles (EVs) in 2023, the demand for reliable and safe EV charging infrastructure is more critical than ever. Charging points are the backbone of the EV ecosystem, and ensuring their safety through rigorous testing is paramount to avoid potential hazards.
This blog will guide you through the essential steps to ensure the safe testing of EV charging points, highlighting best practices and key considerations.
Current Status of Electrical Vehicle (EV) in New Zealand
‘The number of EVs on New Zealand roads has increased significantly in recent years and will continue to grow. The rate of EV ownership has been increasing exponentially over recent years, and in 2023 more than one in four (27.2%) cars purchased were either battery electric or plug in hybrid. ’— EECA.
During 2022 and 2023, the new passenger car market in New Zealand is experiencing a significant shift towards electric vehicles (EVs) as part of country’s broader commitment to sustainability and reducing carbon emissions. The government has introduced various incentives, such as rebates for EV purchases and investments in charging infrastructure, to encourage adoption.
However, recent insights from EVBD in 2024 reveal that while the market share of fully electric vehicles has noticeably decreased, the actual number of fully electric vehicles has been slowly increasing, now reaching levels similar to those seen in the early months of 2022. Additionally, a 2023 EECA survey revealed that EV owners are calling for more public charging facilities to support the expanding EV community.

With the rising demand for better infrastructure, New Zealand is poised for continued progress in electric mobility, both for private users and commercial fleets. The push for more charging points highlights the ongoing evolution of the EV landscape in the country.
Number of Public EV Charging Points
As of April 2024, there are over 1,200 public charging stations across the country, with a mix of standard and fast-charging options. These charging points are strategically located in urban centres, highways and popular tourist destinations. Despite this growth, the demand for additional public charging facilities remains high, particularly in more remote areas and densely populated regions.
Ensure that you use the right charger for your vehicle and before your next adventure, to locate chargers for powering your EV, we recommend the 👉EV Roam website, Plugshare app or NZTA EV Charging Station database.
Electrical Safety Testing of EV Charging Points
The primary focus of EV charging point testing is electrical safety. This involves checking for potential risks such as short circuits, insulation failures and ground faults.
Key tests include:
Insulation Resistance Test: Ensures that the insulation between electrical conductors is adequate to prevent accidental contact and electrical leakage.
Dielectric Withstand Test: Verifies that the charging point can handle high voltage without breaking down.
Ground Continuity Test: Confirms that all metallic parts of the charging station are properly grounded to avoid electric shock.
Earth Leakage Test: Measures any leakage current to ensure that it is within safe limits.
Polarity Check: Ensures that all connections are correctly wired.
Load Testing: Simulates the charging of an EV to assess the performance of the charging station under normal operating conditions, ensuring it can handle the maximum load without overheating or failure.
Residual Current Device (RCD) Test: Verifies the proper operation of the RCD, which is designed to protect against electric shock by breaking the circuit in the event of a fault.
Functionality Testing: Checks that all operational features, such as start/stop buttons, indicators and communication interfaces, are working correctly.
Environmental Testing (if applicable): Assesses the charging station's ability to operate safely in various environmental conditions, such as extreme temperatures, humidity and exposure to dust or water.
Thermal Imaging (optional but recommended): Thermal imaging provides a non-invasive method to detect overheating components or connections that may not be identified by other tests.
At TESTntel, we provide both electrical compliance testing (Test & Tag) and thermal imaging services, ensuring your equipment is safe, efficient, and reliable.

Who Can Perform EV Charging Point Testing?
Testing of EV charging points should be carried out by qualified and authorised electrical professionals who are trained in the specific requirements of EV charging systems. These professionals must be familiar with relevant standards, such as AS/NZS 3760:2022 and SNZ PAS 6011/6010, and possess the necessary certifications to perform both electrical compliance testing and any additional inspections, such as thermal imaging.
Compliance with New Zealand Standards
Adhering to industry standards is essential when testing EV charging points in New Zealand. Compliance with relevant standards, such as SNZ PAS 6011:2023 (the Residential Electric Vehicle (EV) Charging Standard) and SNZ PAS 6010:2023 (the Commercial Electric Vehicle (EV) Charging Standard), ensures that your EV charging infrastructure meets the top safety, performance and reliability requirements.
Recommended Testing Frequency for EV Charging Points
In New Zealand, there is no specific requirement for a charging cable to undergo Portable Appliance Testing (PAT). However, for commercial chargers, it is recommended to undergo a yearly inspection to confirm that the changes have not compromised its safety or functionality.
However, test intervals may vary depending on specific manufacturer recommendations, the environment in which the charging station is located and applicable local or national regulations.
