AP20 sits at the “fine” end of New Zealand’s All Particles (AP) grading system. This means it contains a full spread of particle sizes up to 20mm, allowing it to compact into a dense, stable surface. Contractors choose AP20 when they need a top layer that feels smooth underfoot and performs well under vehicle traffic. Its fines help bind the surface, reducing loose stones and creating a tidy, professional finish.
AP30’s mid‑sized grading makes it one of the most adaptable aggregates in the AP range. It compacts more easily than AP40 & AP65 while still providing greater structural strength than AP20. This makes it perfect for rural accessways, lifestyle block driveways, and machinery yards where a strong base is needed without the heavier compaction equipment required for AP40.
AP65 sits at the largest end of New Zealand’s All Particles (AP) grading system. Its large stone size creates a strong, interlocking base that resists movement, rutting, and pumping under extreme pressure. Contractors choose AP65 when they need a foundation that can support heavy trucks, diggers, loaders, tractors, and industrial equipment.
Our landscaping bark is designed to enhance both the appearance and health of your garden. With its natural colour and clean chip size, bark creates a neat, professional look while offering practical benefits that support long‑term plant growth. It’s suitable for residential gardens, commercial landscapes, rental properties, schools, community spaces and new builds.
Blue Shale stands out due to its natural blue‑grey tone, which gives outdoor spaces a clean, contemporary look. Unlike standard grey aggregates, Blue Shale brightens driveways and pathways, making properties look well‑maintained and professionally finished.
Builders Mix saves time by providing a ready‑to‑use blend of sand and stone. When combined with cement, it produces strong concrete suitable for a wide range of building applications. Its consistent grading ensures reliable strength and performance.
Used predominantly as a garden mulch, mix with topsoil or garden dirt as it contains lots of natural, nutrient dense materials after it has been used in calf pens during calving.
EcoSure Cement is engineered to reduce carbon emissions during production, making it a smarter choice for environmentally aware builders, landscapers, and DIY users. Golden Bay achieves this through improved manufacturing processes and optimised clinker content, resulting in a lower‑carbon cement that still meets New Zealand’s strict performance standards.
KeriGreen’s compost is produced using high‑quality organic materials that break down into a rich, dark, crumbly blend packed with nutrients. It’s designed to improve soil structure, increase fertility and support healthy root development. This compost is screened for consistency, making it easy to spread and mix into existing soil.
Sand provides stability, drainage, and structure in a wide range of applications. In construction, it is used for concrete mixes, mortar, and paving bases. In landscaping, sand improves soil aeration, supports plant growth, and creates smooth, level surfaces for pathways and play areas.
Drainage Chip is screened to remove fines, ensuring water can move freely through the material. Its smaller size makes it ideal for tight spaces, shallow drains, and areas where larger drainage metal would be too coarse. It is also widely used as a decorative stone due to its clean appearance and consistent grading.
Drainage Metal is specifically screened to remove fines, ensuring water can pass through easily. This makes it ideal for French drains, retaining wall backfill, septic systems, and areas prone to waterlogging. Its clean, angular stones interlock well, providing stability while maintaining open voids for water flow.
Gabion Rock is chosen for its durability, weight, and ability to interlock within gabion baskets. It provides structural stability while allowing water to pass through, reducing pressure behind retaining walls. Its natural appearance also makes it popular for decorative landscaping.
KeriGreen’s Garden Mix is crafted to provide the ideal balance of organic matter, nutrients and structure. It is blended to be light enough for easy planting yet dense enough to retain moisture and support healthy root development. This makes it suitable for a wide range of gardening and landscaping applications.
