What Should I Check Before Buying A Second-Hand Caravan in New Zealand?

Buying a second-hand caravan in New Zealand can be a smart way to enjoy freedom and adventure without the full price of a new model.

However, older caravans can come with hidden problems - from water leaks to mechanical issues - that may cost thousands to fix. Knowing what to check before you buy can save you money and stress.

This guide will help you make an informed and safe purchase, whether you’re buying from a private seller or a dealer.

1. Structural condition

Start with the caravan’s overall body and structure:

• Exterior panels: Look for dents, rust, corrosion, or any bulging on the side of the caravan;

• Roof and seams: Check for cracks, water damage, weakened seals, and dips in the roof, especially around skylights; and

• Chassis and suspension: Inspect for rust, cracks, and any bent or damaged components.

Tip: Tap lightly on panels - a hollow sound may indicate water damage or rot.

2. Water leaks and plumbing

Water damage is one of the most common issues in second-hand caravans. Check:

• Around windows and roof vents for leaks inside the caravan;

• Internal walls and flooring for soft spots or discolouration - make sure to check the top cupboard along roofline; and

• Plumbing system: taps, grey and fresh water tanks, and drainage pipes.

Caravans in NZ with self-containment certification (NZS 5465) should have properly functioning tanks, and plumbing with appropriate breathers and water seals (smell traps).

3. Electrical and gas systems

Electrical and gas safety is critical:

• 12V and 240V systems: Check lights, outlets, and battery condition (check the battery for any bulging sides);

• Appliances: Confirm the fridge, stove, and heating systems work properly; and

• Gas bottles and fittings: Ensure connections are secure and up to NZ safety standards (make sure the regulator setup has a test point and isolation valve).

Ask for service records for any appliances or installations.

4. Tyres, Wheels, and Brakes

Check the towing safety components:

• Tyres: Look for wear, cracking, or uneven tread (if a caravan has been stationary for too long, it'll get flat spots on the tyres);

• Wheel bearings: Spin each wheel to detect noise or roughness; and

• Brakes and suspension: Test brake responsiveness and check shocks and springs.

A poorly maintained wheel assembly can be dangerous on NZ roads, especially when towing long distances.

5. Interior Condition

Inspect the inside of the caravan:

• Flooring, cupboards, and upholstery for wear or water damage.

• Doors and locks for smooth operation.

• Check for odours - musty smells almost always indicate hidden water issues.

6. Documentation and Certification

Always verify the caravan’s paperwork:

• Warrant of Fitness (WoF) and registration;

• Green self-containment certification (if applicable);

• EWOF and gas endorsement;
  

• Service and maintenance records (not as important); and

• Ownership and insurance history (not as important).

This ensures the caravan is legally compliant and safe to tow.

7. Road Test

Before buying, take the caravan for a short road test:

• Assess towing stability and handling;

• Listen for unusual noises from suspension or brakes; and

• Check that lights and indicators work properly.

8. Red Flags to Watch For

Avoid caravans that show:

• Extensive rust or water damage;

• Broken or missing parts;

• Poorly maintained tyres or brakes; and

• Lack of service or safety documentation.

If in doubt, bring a professional inspector - a small fee can save thousands in the long run.
