Pine vs hardwood fence decision made simple: durability, cost, looks and upkeep compared — and where each timber earns its place on NZ boundaries.
Choose a timber fence in New Zealand and you've really made half a decision — the pine vs hardwood fence question still waits. Treated radiata pine builds the overwhelming majority of the country's fences, while imported hardwoods like kwila and garapa build its feature screens and showpieces, and the two occupy genuinely different roles.
This comparison covers what each timber actually delivers: durability, cost, workability, the maintenance each one asks for, and a couple of practical quirks — like hardwood tannin stains on new concrete — that nobody mentions until it's too late.
Pine vs Hardwood Fence: The Short Answer
In short: treated pine is the right call for most New Zealand fencing — economical, readily available, takes treatment deeply, and paints or stains to any look. Hardwood earns its substantial premium on feature fencing, battened screens and high-visibility areas where its density, fine grain and rich colour do work pine can't.
Pine's durability comes from its treatment; hardwood's comes from the timber itself. Both routes reach a long-lived fence — they just charge differently for the trip.
Long boundary in pine, feature metres in hardwood is the pattern most Auckland projects settle into, and for good reason.
Durability: Treatment vs Density
Radiata pine is not naturally durable — its superpower is accepting preservative treatment right through the sapwood, which is why correctly graded treated pine posts and palings serve for decades. The treatment stamp is the durability; our grades guide explains exactly which stamp goes where.
Dense hardwoods like kwila resist decay and insects by nature, with treatment unnecessary for most above-ground use. Their hardness also shrugs off the knocks and abrasion that mark softer pine.
Either timber fails early when the rules are broken: under-treated pine in the ground, or hardwood detailed without drainage and airflow. Species choose the price; detailing chooses the lifespan.
Cost and Availability
The price gap is real and wide: hardwood palings, battens and rails cost a multiple of their pine equivalents, and the gap compounds across a long boundary. That's the single biggest reason pine dominates.
Pine is also everywhere — consistent grades from every merchant, replacements always matchable. Imported hardwood supply varies by species and season, and matching a batch years later for repairs can take hunting.
If hardwood tempts you, responsibly sourced stock matters too — ask for certified or verified-origin timber, which reputable suppliers can document.
Looks, Finishing and the Tannin Surprise
Pine is the blank canvas: paint it any colour, stain it any tone, and refresh the look whenever tastes change. Its knots and grain read casual rather than crafted, which painting hides entirely.
Hardwood is the statement: oiled kwila and garapa glow deep red-brown, vertical hardwood battens are the signature of contemporary NZ architecture, and even weathered grey hardwood looks deliberate.
The surprise: many hardwoods, kwila especially, bleed tannins when new — dark stains that wash onto concrete paths and render below. It's manageable with pre-washing and timing, but plan for it before installing hardwood above fresh concrete.
Workability and Fixings
Pine builds fast: easy cutting, nails and screws drive straight in, raked slopes and custom fits cost little extra labour. Hardwood's density makes everything slower — pre-drilling is standard, blades dull faster, and that labour difference belongs in any honest quote.
Fixings follow the timber: quality galvanised suits most pine fencing, while hardwood demands stainless steel — its natural extractives corrode and stain around ordinary fixings.
Weight matters too: hardwood rails and palings load posts and footings more, which good builders account for in the structure.
Choosing for Your Project
Run the split-decision: pine for the perimeter where metres are long and budgets real, hardwood where eyes and hands actually land — the entrance fence, the deck screen, the courtyard battens. Most properties want exactly that mix.

Frequently Asked Questions
On feature fencing and screens where its density, grain and colour are on show — often yes. Across long boundary runs, treated pine delivers comparable service life for a fraction of the price, which is why most projects mix the two.
Both reach decades when correctly specified — pine through its treatment grades, hardwood through natural durability. Detailing, drainage and maintenance influence lifespan more than the species choice does.
Tannin bleed — new hardwood releases dark extractives in rain, which mark concrete and render. Pre-washing the timber and protecting surfaces during the first months manages it; it eases as the timber weathers.
Yes — stainless steel throughout, with pre-drilling standard. Hardwood extractives corrode bright and even galvanised fixings, leaving black stains around every screw head.
Stains can take pine toward hardwood tones convincingly at footpath distance, at a fraction of the cost. Up close the grain and crispness differ — which is why the entrance metres are where hardwood spending makes sense.
