Wooden Chopping Boards NZ: The Kiwi Kitchen Guide to End Grain, Long Grain & Wood Fibre Boards
A good chopping board is the most-used tool in a New Zealand kitchen after your knife, yet it's the one most of us think about least. This guide from Michael Joyce, the NZ home of Zassenhaus and Swiss Diamond, explains how end grain, long grain and wood fibre boards work, why they beat plastic, why glass and marble boards wreck your knives, and the simple care tricks that make a wooden board last for decades.
End grain vs long grain vs wood fibre chopping boards: what's the difference?
Think of wood as a bundle of drinking straws glued together. Those straws are the wood fibres, and the way a board is cut decides whether your knife lands on the ends of the straws or along their sides. That one detail changes how a board feels, how it ages and how long your knives stay sharp.
End grain chopping boards: the knife-friendly, self-healing choice
An end grain chopping board is made from short blocks of timber stood on end and glued into that familiar checkerboard pattern. Your knife meets the tips of the fibres, slips between them, and the fibres close back up once the blade lifts away. That's why end grain boards are often called "self-healing": cut marks fade, the surface stays smooth, and your knife edge stays sharp for longer. They're the board of choice for butchers and serious home cooks.
The trade-off is weight and care. End grain blocks are thick, heavy and thirstier for oil, and they must never go in the dishwasher. In return, they last for generations.
Long grain chopping boards: the everyday all-rounder
A long grain cutting board (also called edge grain) is made from strips of timber laid with the fibres running the length of the board. Knives slice across the fibres rather than between them, so you'll see light cut marks over time. Long grain boards are lighter, slimmer, more stable against warping and usually more affordable, which makes them a great first wooden board and a beautiful serving board for cheese and charcuterie.
Swiss Diamond makes its long grain and herringbone butcher's blocks from acacia, a dense hardwood with natural oils that help it shrug off water.
Wood fibre chopping boards: slim, non-porous and dishwasher safe
A wood fibre cutting board is made from compressed natural wood fibres bonded into a dense, thin sheet. It keeps the knife-friendly feel of wood but adds the convenience people usually buy plastic for. The Swiss Diamond Wood Fibre Chopping Board is just 9 mm thick, has a non-porous surface that resists stains and odours, is heat resistant to 180°C, sits on non-slip silicone feet, has a juice groove, and is dishwasher safe. It's the board to grab for raw chicken, beetroot and anything else you'd rather sterilise in the dishwasher.

Why wooden chopping boards are better than plastic
Plastic boards became popular because they looked cleaner. The science has since caught up, and it favours wood.
1. Plastic boards shed microplastics into your food
A 2023 study published in the American Chemical Society journal Environmental Science & Technology found that chopping on plastic boards releases microplastic particles into food. The researchers estimated a person could be exposed to tens of millions of polyethylene and polypropylene microparticles a year from their chopping board alone. Wooden and wood fibre boards don't add plastic to your dinner.
2. Knife grooves in plastic are a hiding place for bacteria
Every cut leaves a tiny groove in plastic, and those grooves are hard to clean, even in the dishwasher. Research led by food microbiologist Dean Cliver at the University of California, Davis found that bacteria placed on wooden boards dropped away quickly and couldn't easily be recovered, while knife-scarred plastic boards held onto bacteria in their grooves. Dense hardwoods like oak and acacia are naturally tight-grained, and properly cleaned and dried wood is a hostile place for bacteria.
3. Wood protects your knives
A good knife is an investment. Wood gives slightly under the edge, so it stays sharper for longer. Hard plastic grips and drags the edge, and cheap plastic boards often get thrown out when they're deeply scored, adding to landfill.
4. Wood lasts longer and looks better doing it
A well-oiled Zassenhaus end grain block can be lightly sanded and refreshed for decades. A plastic board just gets more scratched and stained. Wood is also a renewable material: Zassenhaus uses sustainably sourced oak, acacia and rubberwood, and rubberwood is typically harvested from rubber trees once they've finished producing latex.
Why you should never use glass or marble chopping boards
The short version: glass and marble are much harder than a knife's fine edge needs to land on. Every cut rolls, dulls or chips the edge. Use them for serving or pastry, never for cutting.
Glass chopping boards blunt knives in minutes
Glass is one of the hardest surfaces in your kitchen. When a knife hits it, the thin edge bends over or micro-chips. You'll hear it too: that sharp click is the sound of your knife going blunt. Glass is also slippery, so food and blades skid, which is how cut fingers happen. Drop one on a tiled floor and you've got a dangerous mess.
Marble boards are hard, cold and acid-sensitive
Marble looks stunning, but it's still far harder than wood, so it dulls knives in the same way. Marble is made of calcium carbonate, which means lemon juice, vinegar, tomatoes and wine can etch dull marks into the polished surface. Keep marble for rolling pastry or presenting cheese, and do your cutting on wood.
Better choice: serve on wood. A Zassenhaus Acacia Serving Board or Zassenhaus Cheese Board & Glass Dome gives you the wow factor at the table, and you can slice right on it without hurting your knife.

12 tricks & tips for wooden chopping boards
- Oil it when it looks thirsty. When the timber looks pale or dry, rub in a food-grade mineral oil or board oil with a soft cloth, leave it overnight and wipe off the excess. New end grain boards drink a lot, so oil them weekly for the first month, then monthly.
- Skip the olive oil. Cooking oils like olive, canola and sunflower can go rancid in the wood and leave a sour smell. Stick to food-grade mineral oil or a beeswax board butter.
- Wash fast, dry upright. Wash with warm soapy water straight after use, rinse, towel dry and stand the board on its edge so air reaches both sides. Never soak a wooden board in the sink.
- Keep wood out of the dishwasher. Heat and water make wooden boards swell, crack and warp. If you want dishwasher convenience, that's what the Swiss Diamond Wood Fibre board is for.
- Freshen with lemon and salt. Sprinkle coarse salt over the board, scrub with half a lemon, leave for five minutes, then rinse. It lifts garlic, onion and fish smells and brightens stains naturally.
- Sanitise with white vinegar. After cutting raw meat on wood, wipe the board with undiluted white vinegar, then wash and dry as normal.
- Use both sides. Flip your board regularly so it wears and absorbs moisture evenly. This also helps prevent cupping.
- Stop the slide. Place a damp tea towel or a non-slip mat under a wooden board before chopping. Swiss Diamond Wood Fibre boards already have silicone feet.
- Keep separate boards for raw meat. Use one board for raw meat, poultry and seafood and another for ready-to-eat foods like bread, fruit and salad to avoid cross-contamination.
- Sand away the years. If a long grain board gets fuzzy or scored, sand lightly with fine sandpaper (around 180 then 240 grit), wipe clean and re-oil. It'll look close to new.
- Slice on the board, then serve on it. A Swiss Diamond Herringbone or Zassenhaus serving board goes straight from bench to table. Fewer dishes, more wow.
- Hone your knife, not your board. Pair your board with regular honing. A sharp knife on a wooden board is safer than a blunt one because it doesn't slip.
Caring for wooden chopping boards in New Zealand's climate
From humid Auckland summers to dry Central Otago winters, New Zealand weather is tough on timber. A few local habits keep your board flat and crack-free:
- Winter: heat pumps, log burners and wood fires dry the air fast. Keep boards well away from heat sources and oil a little more often between May and August.
- Summer: in humid areas like Auckland, Northland and the Bay of Plenty, make sure boards dry completely and stand upright so mould can't take hold.
- Off to the bach: heading to the bach for the holidays? Oil your board before you go and store it upright in a ventilated spot, not sealed in a plastic bag.
- Hard water areas: if you see a whitish film, a quick wipe with white vinegar removes mineral residue before you oil.
Chopping board FAQs
What is the best type of chopping board in NZ?
For most New Zealand kitchens, a wooden board is best. An end grain board like the Zassenhaus End Grain Oak is the most knife-friendly and long lasting, a long grain board like the Swiss Diamond Long Grain Acacia is a lighter everyday choice, and a Swiss Diamond Wood Fibre board is the most convenient because it's dishwasher safe.
Is an end grain or long grain chopping board better?
End grain boards are better for knife edges and hide cut marks because the blade slips between upright wood fibres. Long grain boards are lighter, more affordable and less prone to warping. Serious cooks often choose end grain for main prep and long grain for serving.
Are wooden chopping boards more hygienic than plastic?
Research from the University of California, Davis found bacteria die off faster on clean wooden boards than in the knife grooves of used plastic boards. Wood also avoids the microplastics plastic boards release, so a well-cared-for wooden board is a cleaner, healthier choice.
Why shouldn't you cut on a glass or marble board?
Glass and marble are much harder than wood, so they roll and chip your knife's edge, making it blunt quickly. They're also slippery, which makes cutting less safe. Marble is etched by acids like lemon juice. Use them for serving or pastry only.
Can wooden chopping boards go in the dishwasher?
No. Solid wooden boards, including Zassenhaus end grain blocks and Swiss Diamond acacia boards, should be hand washed. The exception is the Swiss Diamond Wood Fibre Chopping Board, which is dishwasher safe.
How often should I oil my wooden chopping board?
Oil a new board weekly for the first month, then about once a month, or whenever the wood looks dry or pale. Use food-grade mineral oil or board butter, not cooking oil.
What is a wood fibre chopping board?
A wood fibre chopping board is made from compressed natural wood fibres formed into a thin, dense, non-porous sheet. It's knife friendly like wood but resists stains and odours, and the Swiss Diamond version is heat resistant to 180°C and dishwasher safe.
