Different Gas Pressures and Burner Types In New Zeeland

High Pressure vs Low Pressure Gas Burners in New Zealand

When it comes to buying your first gas stove in New Zealand, it is almost impossible to avoid seeing different shops advertise burners as “high pressure” or “low pressure.”

For many customers this becomes confusing very quickly.

In this guide we explain what these terms actually mean, how LPG systems work in New Zealand, and how to choose the right burner for your cooking needs.

High Pressure vs Low Pressure

One important thing to understand is that standard LPG gas bottles in New Zealand generally operate within a similar pressure range regardless of bottle size.

Whether it is a:

4kg bottle
9kg bottle
13kg bottle

the internal cylinder pressure is usually similar. Typical LPG cylinder pressure commonly ranges between This pressure fluctuates mainly depending on external temperature. Hot weather increases cylinder pressure while cold weather reduces it.

So if the bottles contain similar pressure, what creates a high pressure or low pressure gas system? The answer is the gas regulator.

High Pressure vs Low Pressure Gas Regulators

In New Zealand there are generally two common regulator categories used with LPG cooking appliances.

Low Pressure Regulators

Low pressure regulators reduce the gas pressure down to approximately:

These are commonly used for:

BBQs
Camping cookers
Standard household gas appliances
Outdoor cooking burners

Low pressure systems provide safer and more controlled cooking for most family situations.

High Pressure Regulators

High pressure regulators allow significantly more gas flow to the burner.

A common example is: 20 PSI≈138 kPa ( there are 10PSI and 5PSI versions also available)

High pressure systems are commonly used for:

Commercial wok burners
Large seafood boils
Fast boiling applications
Outdoor catering
High heat cooking

Compared to low pressure systems, high pressure burners can produce dramatically more heat output.

Gas Safety and Regulators

Because high pressure regulators allow substantially more gas flow, it is extremely important never to use a high pressure regulator on a burner designed only for low pressure operation.

Unfortunately, many LPG fittings used in New Zealand can physically connect even when they are not the correct setup. This can lead to dangerous situations when incorrect regulators are matched with unsuitable appliances.

Using an incorrect regulator may cause:

Dangerous flare-ups
Overheating
Fire hazards
Damage to the appliance
Serious injury

Even if a regulator physically fits your burner, it does not mean it is safe to use.

Always use the regulator specified for the appliance.

NZ Gas Safety Compliance

When purchasing a gas burner or regulator, make sure the equipment complies with New Zealand gas safety standards.

Certified appliances normally include a compliance plate, approval label, or certification marking.

Using non-compliant equipment may create serious safety risks and could potentially affect insurance claims if property damage occurs due to unsafe installations or negligence.

How To Choose the Right Gas Burner

Many buyers focus only on maximum heat output, but choosing the correct burner should depend on your intended use.

Low Pressure Burners Are Ideal For:

Family cooking
Fried rice
Steaks
Camping
General outdoor cooking
Safer day-to-day use

For most households, a quality low pressure burner provides more than enough heat.

High Pressure Burners Are Better For:

Large family gatherings
Commercial-style wok cooking
Large stock pots
Seafood boils
50L to 100L cooking pots
Very fast cooking

High pressure systems require more attention while cooking because the heat output is extremely intense. Food can burn quickly if left unattended.

However, for certain cooking styles — especially high heat Asian cooking and very large batch cooking — a high pressure burner can offer major performance advantages.
