Gas fireplaces available in New Zealand include freestanding gas fires (sit on the floor, connect to a flue, available in modern and traditional styles), inbuilt gas fires (built into a wall or existing fireplace opening, sleek modern look), gas log fires (realistic log-effect flames, can be inserted into an existing open fireplace), and balanced-flue gas fires (sealed unit that draws air from outside and exhausts through the same wall vent — no chimney required). Popular brands in NZ include Rinnai, Escea, Masport, and Jayline.

Most gas fireplaces require a flue to exhaust combustion gases safely. Conventional flues run vertically through the ceiling and roof. Balanced flues (power flues) exit horizontally through an external wall, making installation simpler and cheaper. Flueless gas fires are available but have strict room size and ventilation requirements. Your gasfitter will advise on the best flue option based on your home's layout. All flue installations must comply with NZS 5261 and manufacturer specifications.

Modern gas fireplaces are 75 to 90 percent energy efficient, compared to 10 to 20 percent for an open wood fire. This means more heat goes into your room and less is lost up the flue. Look for the energy rating label when comparing units. Gas fires heat a room quickly and can be controlled with a thermostat or remote control for consistent temperature. Running costs depend on gas prices and usage — a typical gas fire costs $1 to $3 per hour to run on natural gas.
