With over 15 years of experience, Heartland Containers provides expert shipping container modifications across the South Island. From secure storage to customised workspaces, every container is built for durability, security, and practicality.
Shipping containers are strong and versatile, but they don’t always meet your needs straight out of the box. Poor ventilation, restricted access, and temperature control issues are just some of the challenges you might face.
At Heartland Containers, we specialise in modifying brand-new and used containers across the South Island. Whether you need better ventilation, extra security, or a fully customised workspace, we have the expertise to get it done.
We customise containers to work for you. With quality materials, expert craftsmanship, and a focus on durability, we make sure your container is practical, secure, and built to last.
Standard shipping containers are airtight, leading to poor airflow and condensation that causes mould, rust, and damage. Extreme temperatures make them too hot in summer and freezing in winter, unsuitable for sensitive goods or comfortable use. While refrigerated containers offer temperature control, standard units need modifications for better ventilation and climate regulation.
Adding vents, whirlybirds, or an air conditioning system helps regulate airflow and prevent moisture buildup. Insulation or climate control modifications can also maintain stable internal temperatures, protecting your goods year-round.
Standard containers come with double doors at one end, which may not suit all needs. If you need quick access to stored goods, frequent loading and unloading, or workspace entry, these doors can be inconvenient. Without modifications, using a container for retail, workshops, or specialised storage becomes difficult.
Installing side doors, roller doors, or custom entry points allows for better accessibility and ease of use. These modifications make moving items in and out more efficient while adapting the container for different purposes.
A standard container has no built-in lighting, making the interior dark and difficult to navigate. If used for storage, workspace, or retail, poor visibility can slow down operations and create an unsafe environment. Relying on external light isn’t practical, especially in enclosed or frequently accessed areas.
Adding windows, skylights, or electrical lighting improves visibility and usability. These modifications transform a container into a practical space that’s safer and more efficient.
While shipping containers are made of steel, their standard locks and doors may not be secure enough for high-value items. Break-ins are still possible, especially in remote or unattended locations. Weak locking mechanisms can be a risk if you’re storing tools, machinery, or stock.
Reinforced locks, security bars, and alarm systems add extra layers of protection. These upgrades make your storage container more secure for storing valuable equipment and assets.
A standard container isn’t always the right fit—but we’ll make sure it is. Whether you need a simple modification or a fully customised setup, Heartland Containers has the expertise to deliver.
Whether for business, industry, or personal use, a customised container can be built to match specific requirements. At Heartland Containers, we create a container that works for
your needs.
Modifying a shipping container can turn it into a practical workspace, storage unit, or living space. To get the best result, consider these key factors before starting.
Shipping containers come in 10ft, 20ft, and 40ft sizes, with standard and high-cube options. Choosing the right one depends on available space, transport logistics, and internal layout needs.
Standard container doors may not be enough for some uses, so adding roller doors, personal access doors, or custom entry points can improve accessibility and ease of use.
Containers can become extremely hot in summer and freezing in winter, making them unsuitable without climate control. If used for storage, work, or accommodation, proper insulation and ventilation are essential.
Options like wall insulation, air conditioning, vents, and whirlybirds help regulate temperature and airflow.
If electricity is required, plan for wiring, power sources, and lighting options. Containers can be fitted with 240V or three-phase power, LED lighting, skylights, or solar systems for off-grid setups.
Security should also be considered, with options like lockboxes, reinforced doors, and alarm systems to protect valuable equipment and stock.
Some modifications require council approval, especially for accommodation, retail spaces, or hazardous material storage. Regulations vary by location, so checking compliance before starting is essential.
Custom modifications like structural changes and electrical wiring can also extend project timelines, so planning ahead is key.

In New Zealand, modifying a shipping container typically requires building consent, especially if it’s for habitation or commercial use. Regulations vary across the country, so it’s important to discuss your project with the local council to ensure compliance.
Depending on factors like environmental impact and placement, resource consent may also be needed. Engaging with local authorities early helps avoid delays and ensures your container meets legal requirements.
Yes, a modified shipping container can be used for commercial purposes in New Zealand, but container conversions must comply with local building and zoning regulations. Depending on the location and intended use, you may need building consent, resource consent, or both before installation.
Features like insulation, plumbing, and electrical fit-outs must meet industry standards to ensure safety and compliance. It’s important to check with your local council before proceeding to avoid any legal or operational issues.
Yes, weight limitations apply when modifying shipping containers, as excessive alterations can impact structural integrity and transport regulations. In New Zealand, the standard road weight limit for a container and its cargo combined is 24 tonnes. However, with a permit and appropriate trailer, this can be increased to 30 tonnes.
Major modifications like heavy additions or structural changes must meet building and engineering standards. If a container exceeds safe weight limits, reinforcements or approvals may be necessary before transport or installation. At Heartland Containers, our on-site engineers ensure all modifications meet regulations while maintaining quality and competitive prices.
Yes, using a modified shipping container as a home in New Zealand usually requires building consent to ensure it meets the Building Code. Councils assess factors like insulation, ventilation, structural integrity, and drainage before granting approval.
Resource consent may also be needed depending on the location and local zoning rules. At Heartland Containers, we help bring your idea to life by creating high-quality container conversions that turn your dream home into reality.
Yes, a shipping container home can be connected to utilities like water and electricity, but it must meet New Zealand’s building and safety regulations. Plumbing and electrical work must be carried out by licensed professionals to ensure compliance with local standards.
Depending on the location, you may need council approval for utility connections, especially for sewage and drainage systems. At Heartland Containers, we design container conversions with fully integrated utility options, ensuring a smooth and hassle-free setup for your home.
