On average, the cost of large landscaping rocks in New Zealand ranges from $100 to $600 per ton. Prices can vary significantly based on the type of rock, with common options including river rocks, volcanic rocks, and schist. Additional factors such as the rock’s size, whether it is sourced locally or imported, and the cost of transportation due to the weight and bulk of the rocks also play a crucial role in determining the final price.

Types Of Large Landscaping Rocks Available In NZ

Landscaping rocks are a popular choice for gardeners and designers looking to add texture, structure, and a natural element to outdoor spaces. In New Zealand, the rich geographical diversity offers a unique selection of rocks, each suited for various design needs. Here, we explore the most common types of large landscaping rocks found across the country, detailing their visual characteristics and suitability for different landscaping projects.

River Rocks

River rocks are smooth, rounded stones typically found in the beds of rivers and streams. Their smoothness is a result of years of water erosion. These rocks come in a range of sizes and neutral shades such as grey, brown, and white. The polished, glossy appearance of river rocks makes them a perfect choice for creating serene and rustic water features, dry river beds, and garden borders. Their smooth texture also makes them ideal for areas where foot traffic is common, as they are comfortable to walk on.

Volcanic Rocks

New Zealand’s volcanic history is prominently reflected in its abundance of volcanic rocks, which include basalt and pumice. Volcanic rocks are usually porous and lightweight, making them easy to position in the garden. Their dark, often black color provides a striking contrast to green foliage and brightly colored flowers, making them excellent for accentuating features in a garden. Volcanic rocks are particularly effective in succulent gardens and other xeriscape designs, as they offer good drainage and reflect heat well.


Schist is a type of metamorphic rock that is prevalent in certain regions of New Zealand, notably the Central Otago. It is recognizable by its strong layering and flaky appearance, often shimmering with mica inclusions. The texture and rustic gold to silver-grey colors of schist make it a popular choice for feature walls, fire pits, and as a dramatic backdrop for water features. Schist is also used in stepping stones and patio areas, where its unique texture and color variations can be fully appreciated.

Suitability for Landscaping Designs

Each type of rock offers different benefits and aesthetic appeals, making them suitable for various applications in landscaping:

River Rocks: are best used in areas where a smooth, organic look is desired. They work well in water features and pebble paths, where their rounded edges and soothing colors enhance the natural flow of the design.

Volcanic Rocks: are ideal for bold, statement features. Their unique porous texture and dark color make them suitable for modern gardens where the contrast with plants can create a visually stunning effect.

Schist: offers a more textured, rugged appeal, making it perfect for creating naturalistic landscapes that mimic the wild beauty of New Zealand’s mountainous regions.

Choosing the right type of landscaping rock depends largely on the desired aesthetic and the functional needs of the garden. By considering both the visual appeal and the practical aspects of each rock type, gardeners and landscape designers can create beautiful, durable, and sustainable outdoor spaces.

Factors Influencing The Cost Of Large Landscaping Rocks

When it comes to landscaping, large rocks are often a central feature due to their natural aesthetic, durability, and low maintenance. However, their cost can vary significantly based on several key factors. In this article, we’ll delve into the various elements that influence the pricing of large landscaping rocks, helping you make informed decisions whether you’re planning a garden project or sourcing materials for a landscaping business.

Size and Weight

The size and weight of landscaping rocks play a crucial role in determining their price. Larger rocks naturally require more material and labor to quarry and shape, increasing their cost. Additionally, heavier rocks are more challenging to transport and may need special equipment to move, which can add to the expense. When selecting rocks for your landscaping, consider how the size impacts both the aesthetics and the budget.

Type of Rock

Not all rocks are created equal in terms of pricing. The type of rock can significantly affect how much you pay. For instance, common types like limestone and sandstone are generally more affordable than more exotic or rare varieties such as quartzite or basalt. The rock’s durability, color, and rarity can influence its price, with more unique and aesthetically appealing options often carrying a premium.


Where the rocks come from also impacts their cost. Locally sourced rocks are typically cheaper because they do not incur high transportation costs. In contrast, rocks that are imported from other states or countries can be more expensive due to the logistics involved in moving them long distances. Considering the origin of the rocks can provide insights into their environmental impact and sustainability, as well as their cost.

Transportation and Delivery

Transportation and delivery costs are significant factors in the overall price of large landscaping rocks. The further the rocks need to be transported, the higher the cost, especially for heavy materials that require special handling and vehicles. These costs can increase exponentially if the delivery site is difficult to access or requires additional manpower to unload and position the rocks.


Buying in bulk can often reduce the cost per unit, making it a cost-effective option for large projects. Many suppliers offer discounts for larger orders, which can be beneficial for both residential customers working on big projects and commercial clients. On the other hand, purchasing individual pieces might be necessary for smaller, more detailed work but can be more expensive in terms of both the price per rock and the associated handling fees.

When planning to purchase large landscaping rocks, it’s important to consider these factors to budget effectively and achieve the desired aesthetic outcome. By understanding how size and weight, type of rock, source, transportation, and quantity affect costs, you can better navigate the complexities of sourcing landscaping materials and make choices that align with your project needs and financial constraints. Whether you’re a homeowner looking to enhance your garden or a professional landscaper sourcing materials for various projects, keeping these cost factors in mind will help you maximize your investment in landscaping rocks.

Factor in delivery costs: Large rocks are heavy, and delivery can be costly. Include this in your budget.

Buying Tips And Considerations

When looking to enhance your garden or outdoor space with landscaping rocks in New Zealand, there are several important considerations to keep in mind. This guide provides comprehensive insights into where to buy, how to check for quality, tips for negotiating prices, and the best times of the year to make your purchase. 

Where to Buy Landscaping Rocks in New Zealand

Finding the right supplier is crucial when purchasing landscaping rocks. New Zealand boasts a variety of local quarries, garden supply stores, and specialized landscaping suppliers that offer a range of rocks suitable for different design needs. Major cities like Auckland, Wellington, and Christchurch have numerous options but don’t overlook local, smaller suppliers in regional areas, which might provide unique local stones not available elsewhere. Additionally, online marketplaces can be convenient, but viewing the product in person is often recommended to fully appreciate the texture and color of the rocks.

Quality Check: Assessing the Quality of Landscaping Rocks

Quality is paramount when selecting landscaping rocks. You want to ensure that the rocks are durable and suitable for the New Zealand climate. When assessing rock quality, check for uniformity in texture and color, depending on your project needs. Examine the rocks for any signs of cracking or excessive weathering, which could affect their longevity and appearance. Consulting with a specialist at the point of purchase can provide additional assurance that the rocks meet your landscaping requirements.

Negotiation Tips: Can You Negotiate Prices and How?

Yes, it is often possible to negotiate the price of landscaping rocks, especially when purchasing in large quantities. To successfully negotiate, it’s helpful to research the average prices in your area and gather quotes from several suppliers. Demonstrating knowledge of the market can make you a more formidable negotiator. It’s also effective to visit suppliers in person, as building a rapport can lead to better deals. Don’t hesitate to ask for discounts, particularly towards the end of the financial year when businesses are more likely to clear stock.

Seasonal Considerations: Best Times of the Year to Buy

The price of landscaping rocks can vary throughout the year based on demand and supply dynamics. Typically, the end of winter and early spring are when most landscaping projects commence, so prices can be higher due to increased demand. Conversely, late autumn and early winter might offer better deals as businesses seek to reduce inventory before the year’s end. Planning your purchase during these off-peak times can lead to significant savings.

In conclusion, purchasing landscaping rocks in New Zealand requires a bit of planning and consideration but can lead to wonderfully aesthetic and functional enhancements to your property. By understanding where to buy, how to assess quality, negotiate prices, and consider seasonal fluctuations, you can make informed decisions that ensure value for money and a beautiful result in your landscaping projects.

Maintenance And Long-Term Care

When it comes to enhancing your outdoor space, landscaping rocks are a popular choice due to their aesthetic appeal and low maintenance. However, proper upkeep is crucial to ensure these features continue to enhance your garden’s beauty and do not turn into an eyesore or a financial burden over time. Section 6 delves into maintenance tips and explores potential long-term costs associated with landscaping rocks. Here’s a detailed guide to help you manage these aspects effectively.

Maintenance Tips to Preserve the Quality and Appearance of Landscaping Rocks

Regular Cleaning: Over time, dirt, debris, and organic material like leaves can accumulate on your rocks, diminishing their appearance. It’s essential to regularly clean these elements off your rocks. A simple hose down can work, but for more stubborn grime, a mixture of water and vinegar can be used to gently scrub the rocks clean.

Weed Control: Weeds can sprout between landscaping rocks, detracting from the overall look and potentially dislodging the rocks. Regularly pulling weeds and using a geotextile fabric underneath the rocks can prevent unwanted growth.

Check for Erosion: Landscaping rocks can shift due to erosion caused by water runoff. Periodically check the arrangement of your rocks and reposition them if necessary to maintain the intended design.

Sealing Rocks: Some types of rocks benefit from sealing to maintain their color and protect them from elements. Sealants can prevent water absorption and help the rocks resist weathering, keeping them looking new for longer.

Potential Long-Term Costs of Landscaping Rocks

Cleaning Expenses: While regular cleaning can often be done using household items, professional cleaning might be required for tougher stains or larger areas, which can incur costs.

Repositioning and Restoration: Over time, rocks can sink into the soil or be displaced. The cost of repositioning these rocks, either by DIY methods or by hiring professionals, should be considered as a long-term maintenance expense.

Replacement Costs: Although landscaping rocks are durable, extreme weather conditions or accidental damage may necessitate replacements. The cost will depend on the type of rock and its availability.

Professional Maintenance Services: Depending on the scale and design complexity, you might need professional help to maintain the aesthetic and structural integrity of your rock landscaping. This could include regular inspections and the aforementioned cleaning and repositioning services.

Maintaining landscaping rocks is crucial for preserving the aesthetic appeal and structural integrity of your outdoor space. By understanding the necessary upkeep and potential costs involved, you can ensure that your landscaping continues to add value and beauty to your home for years to come. Regular maintenance not only keeps the rocks looking pristine but also helps avoid larger expenses down the line by addressing issues promptly.

Alternatives To Large Landscaping Rocks

When considering a revamp or design of your garden, large landscaping rocks are a common feature, favored for their natural look and durability. However, various alternatives can equally enhance the beauty of your garden, often at a lower cost and with easier maintenance. In this article, we explore some popular alternatives to large landscaping rocks, such as bark, smaller stones, and synthetic options, along with their advantages and disadvantages.

Bark Mulch


Cost-Effective: Bark mulch is significantly less expensive than large landscaping rocks. It’s an ideal choice for covering large areas on a budget.

Soil Health: Bark decomposes over time, enriching the soil with organic matter and improving soil health.

Moisture Retention: It helps the soil retain moisture, reducing the need for frequent watering and thus saving on water bills.


Maintenance: Bark mulch needs to be replenished regularly as it decomposes or gets washed away, which can add up in terms of time and effort.

Pest Attraction: It can attract insects and pests that might be harmful to your garden plants.

Smaller Stones


Variety: Smaller stones come in various colors and textures, offering flexibility in design.

Low Maintenance: Once placed, these stones do not require frequent upkeep. They do not decompose like organic materials, maintaining their appearance over time.


Cost: While generally cheaper than large rocks, high-quality or uniquely colored smaller stones can be quite expensive.

Soil Compaction: Smaller stones can compact the soil underneath, potentially restricting water and nutrient absorption by plant roots.

Synthetic Options


Uniform Appearance: Synthetic landscaping materials, like rubber mulch or faux rocks, provide a consistent look and are available in multiple colors and styles.

Durability: These materials do not degrade over time, maintaining their appearance without needing replacement.


Environmental Impact: Synthetic materials are not biodegradable and can contribute to environmental pollution if not disposed of properly.

Cost: High-quality synthetic options can be as expensive as natural stone, without the added benefits of natural materials.

Choosing the right landscaping elements depends on your specific needs, budget, and the overall aesthetic you wish to achieve. While large landscaping rocks provide a timeless, rugged beauty, alternatives like bark mulch, smaller stones, and synthetic options offer versatile and often more economical ways to decorate your garden. Each option comes with its own set of benefits and drawbacks, so consider your long-term maintenance capacity and environmental impact when making your choice.

Remember, a well-planned garden not only enhances the curb appeal of your home but also creates a personal retreat space that you can enjoy for years to come. Whether you opt for the natural elegance of stone or the practical benefits of synthetic alternatives, your choice should align with your vision of an ideal outdoor space.
