2025 Electrical Compliance Updates: What Every Property Manager Needs to Know

As a property manager in New Zealand, keeping up with regulatory changes is key to ensuring your buildings remain safe, efficient, and compliant. The latest update from the Commerce Commission—the 2025 reset of the Electricity Distribution Default Price-Quality Path (DPP4)—introduces new standards and expectations for electrical systems. While much of the framework is aimed at electricity distributors, these changes have real-world implications for property managers, especially when it comes to maintaining and upgrading electrical infrastructure.

In this guide, we’ll walk you through the main points of the DPP4, explain how they affect your property management responsibilities, and offer practical advice for staying ahead of the curve. Whether you’re new to the field or have years of experience, this resource will help you navigate the evolving landscape of electrical compliance.

Understanding the 2025 Electricity Distribution Default Price-Quality Path (DPP4)

What is the DPP4?

The Electricity Distribution Default Price-Quality Path (DPP) is the regulatory framework that governs how electricity distribution businesses (EDBs) in New Zealand operate. It sets limits on how much these businesses can charge and establishes quality standards for the electricity network. The Commerce Commission reviews and updates the DPP every few years to reflect advances in technology, evolving safety standards, and the needs of consumers. The latest update, DPP4, took effect on 1 April 2025 and will remain in place until 31 March 2030.

How Does This Affect Property Managers?

As a property manager, you play a crucial role in ensuring that the buildings under your care meet all relevant safety and compliance standards. The DPP4 update means that electricity distributors must invest more in maintaining and improving their networks, which can influence the reliability and quality of power supplied to your properties. For you, this translates into a greater need to keep your building’s electrical systems up to date and in line with the latest requirements. 

Key Changes and Their Implications

Stricter Quality Standards

The DPP4 introduces more rigorous requirements for electricity distribution. This means that electricity distributors must ensure their networks are reliable, safe, and efficient. For property managers, this highlights the importance of maintaining your building’s electrical systems to a high standard. Older or poorly maintained systems may not only fall short of these new benchmarks but could also put your property at risk of outages or safety hazards. Staying proactive with upgrades and maintenance helps you avoid compliance issues and keeps your tenants safe.

Revenue Limits and Pricing Adjustments

The Commerce Commission has set new revenue limits for electricity distributors, which could affect the cost of electricity for end users. While these changes mainly impact distributors and retailers, property managers should be aware of the potential for fluctuating energy prices. Investing in energy-efficient upgrades, such as LED lighting and modern switchboards, can help you manage costs and make your property more attractive to tenants and buyers.

Reopener Provisions

The DPP4 framework includes provisions for “reopening” the regulations if unexpected circumstances arise. The Commerce Commission is working on guidance to help stakeholders understand when and how these adjustments might occur. For property managers, this means it’s important to stay informed about potential regulatory changes so you can adapt your management strategies as needed.

Essential Electrical Compliance Tasks for Property Managers

To help you stay compliant and protect your tenants, here are the key areas you should focus on:

1. Switchboard Upgrades

Switchboards are the central hub of your building’s electrical system, distributing power safely and efficiently. However, older switchboards often lack the safety features and capacity required by modern standards. Upgrading your switchboard brings several advantages: enhanced safety through features like Residual Current Devices (RCDs) that prevent electric shocks and fires, improved compliance with current regulations, and better energy efficiency. Modern switchboards also make it easier to integrate new technologies, such as smart systems or renewable energy sources, in the future.

A typical switchboard upgrade involves an initial inspection by a qualified electrician, recommendations for improvements, professional installation, and thorough testing to ensure everything meets safety and regulatory requirements. In many cases, parts of the upgrade will also require third-party inspection for certification.

2. Regular Electrical Inspections and Periodic Verification

Regular electrical inspections are essential for identifying potential hazards and ensuring your property remains safe and compliant. The DPP4 framework and ongoing regulatory changes make these checks even more important. Inspections can reveal issues such as outdated wiring, overloaded circuits, or faulty equipment that could pose risks to your tenants and property.

High-risk installations, such as those involving mains work, hazardous areas, or medical devices, must be inspected by an authorised, independent professional. Certain systems also require periodic verification by competent persons to ensure ongoing safety. Keeping detailed records of inspections and any necessary repairs is a key part of compliance.

For businesses and commercial properties, regular testing and tagging of portable electrical equipment is also required. This process involves inspecting and testing equipment to ensure it’s safe to use, with the frequency depending on the type of equipment and its environment.

3. IQP-Certified Services

An Independent Qualified Person (IQP) is a specialist authorised to inspect, maintain, and report on integrated systems under the NZ Building Code. These systems often include emergency lighting, lifts, escalators, automatic doors, and fire detection systems. Many buildings are required to have these systems inspected and maintained by an IQP as part of their Building Warrant of Fitness (BWOF).

Working with an IQP-certified provider ensures that your critical safety systems are functioning correctly and that your building meets all regulatory requirements. This not only keeps your tenants safe but also gives you peace of mind that your property is fully compliant.

4. Surge Protection and Circuit Breaker Upgrades

Power surges can damage sensitive electronic equipment and pose a fire risk. Installing surge protection devices helps safeguard your building’s electrical systems and appliances. Upgrading to modern circuit breakers provides better protection against overloads and short circuits, further reducing the risk of electrical fires and equipment damage.

5. Energy Efficiency Upgrades

With rising energy prices and stricter regulatory standards, investing in energy-efficient upgrades is a smart move for property managers. LED lighting, smart thermostats, and energy-efficient appliances can significantly reduce your property’s energy consumption and operating costs. These upgrades not only help you comply with new regulations but also make your property more attractive to tenants and buyers.

To get started, consider replacing outdated lighting with energy-efficient LEDs, installing smart energy management systems, and choosing energy-efficient appliances for common areas and tenant spaces.

Practical Steps for Property Managers

To help you stay on top of the 2025 electrical compliance updates, here are some practical steps you can take:

1. Schedule a Professional Electrical Inspection

Arrange for a qualified electrician to inspect your property’s electrical systems. This will help you identify any areas that need upgrading or repair to meet the new standards.

2. Plan and Budget for Necessary Upgrades

Based on the inspection results, work with your electrician to plan and budget for any necessary upgrades—such as switchboard replacements, surge protection, or energy efficiency improvements.

3. Stay Informed About Regulatory Changes

Keep an eye on updates from the Commerce Commission and other regulatory bodies. This will help you anticipate changes and adapt your property management strategies accordingly.
