In the modern era of consumerism and family legacies, the booming storage industry is more than just about keeping possessions safe—it's driven by a complex web of inheritance, urban development, and changing lifestyles. But here’s where it gets controversial: many people overlook how much this industry is shaped by the transfer of wealth across generations and the practical challenges of housing in densely populated areas.
On a typical summer weekday afternoon in Auckland’s bustling city center, a woman dressed in gym attire steps out of an elevator at National Mini Storage, clutching a sizable plastic container labeled simply ‘December/Xmas’. Outside, a steady flow of vehicles come and go, with some drivers loading personal belongings into their storage units and others returning to retrieve their stored items.
Inside the multi-story facility, corridors lined with security cameras stretch out, guarding a range of garage-style spaces with manual roller doors. Think of it as renting out a small 'apartment' for your belongings: for approximately $217 a month, you get about 2 by 1 meters of space, while larger units—comparable to a single-car garage—cost around $532 monthly.
This surge in demand for storage is directly linked to the largest-ever transfer of family wealth in New Zealand’s history—which is expected to reach an astonishing $1.6 trillion over the next 25 years. Along with cash and property, baby boomers and members of the silent generation will pass along vast collections accumulated over a lifetime—collections that include heirlooms, furniture, and memorabilia.
However, finding a place for these heirlooms has become increasingly difficult because of urban housing policies promoting higher-density living—especially in Auckland—where efforts are underway to allow taller buildings along transport corridors and near town centers. The shrinking size of homes means less storage space, even as the volume of possessions passes from one generation to the next.
Sam Scott, a specialist in the self-storage industry at CBRE, highlights a paradox: "Homes are becoming smaller, yet people still have more stuff to store." Currently, New Zealand’s self-storage units are available at a rate of roughly 2.39 units per 100 residents, which is modest compared to the United States, where about a third of the population has rented a storage unit at some point, and 10% are regular renters.
Looking ahead, the demand for storage is poised to grow further, driven by an aging population that tends to accumulate more belongings, the rise of medium- and high-density housing options, and the exponential growth of e-commerce businesses. Many small and home-based businesses rely on storage as a flexible alternative to traditional industrial spaces, allowing them to scale operations up or down rapidly without being tied to long-term lease commitments.
As Scott explains, "In my role, I visit storage sites and hear many personal stories. Traditionally, most households would have a single car in the garage and, perhaps, used the other half for additional storage. But with more apartments and townhouses now, that flexibility is disappearing."
He adds that moving, inheritance, or family members passing away often lead people to seek stored space for transitional periods, until they decide what to do with accumulated belongings. Many also use storage for business inventory, especially e-commerce stock, which benefits from the ability to adjust inventory levels quickly without incurring the costs associated with long-term industrial leases.
The industry is evolving into a corporate landscape, with large firms acquiring smaller operators. For example, Australia’s National Storage REIT was recently taken over by a consortium led by Brookfield Asset Management, in a deal valued at AUD $4 billion (roughly NZD $4.5 billion). This deal sent National Storage’s share price soaring to an all-time high. Similarly, in New Zealand, Kennards—a private Australian company with a market valuation over $4 billion—acquired National Mini Storage’s 13 Auckland sites.
Luxury storage options are available at these larger sites, too. For instance, climate-controlled wine cellars, ideal for collectors, are rentable for around $100 for a 24-case capacity. Meanwhile, themes like location influence pricing: at Total Storage in Invercargill, parking a car costs only $140 per month.
Makala Ffrench Castelli, CEO of the Self Storage Association of Australasia, reports that Auckland has experienced over a 50% increase since 2013 in the amount of self-storage space available per person. Today, New Zealand hosts approximately 129,000 storage units spread across 780 facilities, covering about 1.29 million square meters of storage area, with plans for an additional 12 facilities to come online soon.
Ffrench Castelli emphasizes that demographic shifts—smaller homes, more frequent moves, business expansion needs—are primary drivers behind this growth. She compares New Zealand’s steady market to Australia’s more rapid expansion, owing to its larger population and more intense development activity, but notes both countries share solid long-term fundamentals.
Small operators also play a significant role. In Rotorua, for instance, East Side Storage, owned by a local entrepreneur who prefers to remain unnamed, has expanded from 46 to 120 units over four years by reducing unit sizes, increasing profitability, and providing more flexible storage options, including boats and vehicles for holidaymakers.
While these storage solutions cater to personal needs, another industry has blossomed around helping people manage or downsize their possessions—professional declutterers and organizers. Beks Holmes of The Decluttering & Organising Co. has built a business primarily serving women aged 40 to 60, offering both in-person and online services.
Holmes explains that decluttering is often emotionally challenging—especially when people inherit family belongings after a loved one’s passing or when their children leave home and leave behind clutter. Many clients admit that they’ve often looked around their homes and realized, “None of this is really mine.”
She advocates for clear communication within families about possessions, suggesting that people ask their relatives directly whether they want inherited items like family crystal or silverware. Often, the answer is no, and Holmes encourages her clients to reclaim their space and focus on items that truly make their lives easier or bring joy.
Holmes’s work underscores a broader truth: for many, letting go of possessions involves emotional barriers and long-standing habits of holding onto things ‘just in case.’ Addressing this can be a vital step toward creating a more manageable and meaningful living space.
So, the question remains: Is the thriving storage and decluttering industry a sign of a healthy, adaptable society—or a reflection of deeper issues related to consumerism and attachment? Do we truly need all these possessions, or are we simply holding onto them out of habit or habit, preventing ourselves from living freely?
