Fuel & Performance

A complete guide to NZ firewood species, moisture content, burning efficiency, and getting the most heat from your wood burner. Covers native and exotic species available across New Zealand.

Quick Answer

Burn only dry firewood (under 20% moisture) from high-heat species like manuka, kanuka, or blue gum. Wet or resinous wood causes creosote buildup, poor heat output, and excessive smoke.

Key Takeaways

Firewood moisture content should be below 20% — use a moisture meter to check
Manuka, kanuka, and puriri are NZ's highest-performing native firewoods
Macrocarpa and blue gum are excellent exotic hardwoods widely available in NZ
Pine is fine for kindling but poor for primary heating due to high creosote risk
Driftwood should never be burned — it releases toxic chlorine compounds from salt

Best Firewood in NZ Ranked — Species Comparison With Burn Times, Heat Output, and Prices

Mānuka is the best-performing firewood in New Zealand — it burns the longest, produces the most heat, and creates the least creosote. But at $200+ per cubic metre, it's expensive and hard to source in bulk. For most NZ homeowners, a "hot mix" of 50% pine and 50% hardwood offers the best balance of ignition speed, heat output, burn time, and cost. The single most important factor isn't the species — it's moisture content.

Frequently Asked Questions

What is the best firewood in NZ?

Manuka and kanuka are widely considered the best NZ firewoods for heat output, low smoke, and long burn time. Blue gum and macrocarpa are excellent exotic alternatives.

How dry should firewood be before burning?

Firewood should have a moisture content below 20%. Freshly cut wood is typically 40-60% moisture and needs 12-18 months of seasoning under cover.

Is it safe to burn pine in a wood burner?

Pine can be used for kindling and starting fires, but it burns fast, produces high creosote, and gives poor heat. It should not be your primary fuel.
