If you’re looking for timber that blends beauty, durability, and sustainability, look no further than Marlborough-milled Macrocarpa. Locally sourced and expertly milled, this golden-toned softwood has become a favourite across New Zealand for its natural resilience and timeless character.

From custom slabs to sleepers, Macrocarpa brings warmth and authenticity to every project, and with TNT Milling’s sustainable approach, you can be confident your timber is as good for the planet as it is for your build.

Why Marlborough Macrocarpa Stands Apart

Macrocarpa contains natural oils and resins that protect against decay, rot, and insects — no chemical treatment required for most applications. Its inherent strength makes it ideal for garden beds, beams, decking, and outdoor furniture, delivering decades of performance even in harsh Marlborough weather.

Fun fact: Macrocarpa is classed as a durability class 3 timber, meaning it can last 15 + years above ground without treatment, one of the best results for a softwood species.

Beautifully Unique

Each piece of Macrocarpa is different, showcasing honey-gold hues that age gracefully into a soft silver patina outdoors. It’s fine, even grain and smooth texture make it perfect for indoor furniture, feature walls, and benchtops, bringing nature’s warmth inside.

Sustainably Sourced & Locally Milled

At TNT Milling, our Macrocarpa is locally and sustainably harvested, often from shelterbelt or windbreak trees rather than large-scale felling. This ensures:

✅ Fewer transport miles and a smaller carbon footprint

✅ Timber acclimatised to New Zealand’s climate

✅ Full traceability from log to slab

✅ Support for local Marlborough jobs and forestry

Popular Uses for Macrocarpa

Indoor Applications

Feature slabs or benchtops – highlight the natural grain and tone for show-stopping kitchen or dining pieces.
Furniture and joinery – ideal for dining tables, shelving, and cabinetry.
Wall cladding or panelling – adds organic warmth and texture to modern interiors.

Outdoor Applications

Raised garden beds – non-toxic and naturally durable.
Decking and pergolas – weathers beautifully with minimal maintenance.
Outdoor furniture – benches, tables, and feature pieces with rustic character.
Sleepers and retaining walls – strong, stable, and long-lasting without chemical treatment.

Caring for Your Macrocarpa Timber

Keep your Macrocarpa looking its best with a little TLC:

Allow to dry fully before use — use seasoned timber to prevent movement or cracking.
Oil or seal surfaces with tung or linseed oil to enhance colour and protect from UV.
Elevate sleepers slightly off the ground to extend lifespan.
Clean annually and lightly sand or re-oil as needed to maintain that golden finish.

Pro tip: For outdoor pieces, embrace the natural silvering process — it gives Macrocarpa its signature coastal charm.

Local Timber vs Imports – Why Local Wins

🌱 Sustainability: Fewer transport emissions, less waste.
💪 Strength & Suitability: Grown for NZ conditions.
💼 Community Support: Backing Marlborough’s local trades and sawmills.

Imported timber can’t match the environmental or community value of locally milled wood, and that’s something we’re proud of at TNT Milling.
