But never fear The Firewood Company is here with some red hot tips to ensure your firepit is a roaring success!

We’ll walk you through everything you need to build the perfect outdoor fire pit, what firewood to use, and how to keep your warm weather gatherings safe and smoke-free.

How Do I Choose the Right Location for My Fire Pit?

Before you start building, choosing a safe and functional location is crucial. Here are some factors to consider:

✅ Clearance

Make sure your fire pit is at least 3 metres away from any structures, fences, trees, or overhanging branches. This reduces the risk of fire spreading and keeps smoke away from the house.

✅ Wind Direction

Choose a spot that is naturally sheltered from wind. Strong gusts can cause embers to blow around or smoke to become a nuisance for guests.

✅ Flat Surface

Level ground is essential for a stable fire pit. If your yard is sloped, consider digging into the slope or building a raised platform to create a level base.

✅ Legal Regulations

Before digging, always check your local council regulations for any fire bans, permits, or fire pit rules—especially during the dry summer months in New Zealand.

How to Build a Fire Pit (Step-by-Step)

DIY Fire-pit

You don’t need to be a professional builder to create a beautiful fire pit—just a few basic materials and some good planning with get you off to the right start.

Materials:

• Fire bricks or pavers

• Gravel or sand

• Shovel

• Steel fire ring (optional for longevity and safety)

Step 1: Mark the Area

Use a string tied to a stake or spray paint to mark out your circle—typically 1–1.5m in diameter.

Step 2: Dig the Base

Dig down around 15–20cm. This will help contain the fire and create a natural windbreak.

Step 3: Add Gravel or Sand

Fill the hole with gravel or sand to assist with drainage and provide a solid foundation. Avoid using river stones in your fire pit, as they can retain moisture and potentially explode when heated due to trapped steam. Even though they are plentiful in NZ and absolutely stunning, it could leave you with a fire pit you cannot use safely.

Step 4: Stack Your Fire Bricks

Lay fire bricks or pavers in a circular pattern, at least three layers high. For added stability, stagger the bricks and use construction adhesive or concrete between layers.

Step 5: Install a Fire Ring (Optional)

Adding a steel fire ring inside your brick circle will protect the bricks from direct flames and prolong their life.

What is the Best Wood for Fire Pits? What to Burn and Why

Not all firewood is created equal. Using the right type of firewood can mean the difference between a beautiful, clean-burning fire and a smoky, eye-watering disaster.

At The Firewood Company, we supply a range of seasoned firewood ideal for both indoor heating and outdoor fire pits.

🪵 Gum (Eucalyptus)

• Best for: Long-lasting, hot-burning fires

• Benefits: Burns hot and clean, producing minimal smoke when properly seasoned. Great for keeping warm on cooler spring and summer nights.

• Summer tip: Ideal for outdoor cooking fires and overnight burns.

🪵 Pine

• Best for: Quick-start fires and kindling

• Benefits: Easy to light and burns fast, making it a great base wood. Use it to get your fire going before adding hardwoods like gum.

• Summer tip: Perfect for short fires during BBQs or casual evening hangouts.

🪵 Mixed Hardwood

• Best for: Balanced, budget-friendly fires

• Benefits: A great all-rounder that offers steady heat and low smoke output when dry.

• Summer tip: Ideal for family-friendly backyard fire pits with minimal fuss.

👉 Avoid burning green wood, damp logs, or softwoods with high resin content (unless well-seasoned) as they create excess smoke and creosote buildup. Avoid burning treated wood or driftwood, as they can release toxic chemicals and harmful fumes when ignited—posing risks to your health and the environment.

Summer Fire Safety Tips

While fire pits are a fantastic way to enjoy the outdoors, it’s essential to keep summer fire safety in mind—especially in New Zealand, where fire bans can be enforced during dry seasons.

🔥 Check for Fire Bans

Always check with your local fire authority (like Fire and Emergency NZ) for restrictions before lighting your fire pit.

🔥 Keep a Hose or Bucket Nearby

Be prepared to extinguish the fire quickly if needed. A hose, sand bucket, or fire extinguisher should be within reach at all times.

🔥 Never Leave a Fire Unattended

Even small backyard fires can get out of control fast. Always supervise children and pets near the fire.

🔥 Extinguish Properly

When the night is over, soak the embers thoroughly with water. Stir and repeat until everything is completely cool to the touch.
