Polycarbonate Greenhouses – Strong, Durable, and Built for New Zealand Conditions

Morrifield Polycarbonate Greenhouses are some of New Zealand’s strongest and most reliable greenhouses.
Designed specifically for 6mm twinwall polycarbonate since the 1980s, they offer outstanding durability, high wind resistance and consistent performance in exposed or remote locations.

Why Choose a Morrifield Polycarbonate Greenhouse?

Our polycarbonate greenhouses provide:

• Excellent heat retention and insulation

• Better growing conditions and higher yields

• Long-lasting materials and great value over time

• Low maintenance and easy cleaning

• Protection from UV rays and harsh weather

Benefits of 6mm Twinwall Polycarbonate

Stronger Protection in Tough Weather

6mm twinwall polycarbonate acts like double glazing.
It helps keep warmth inside and shields plants from:

• Heavy rain

• Strong winds

• Hail

• Frost

This reduces crop damage and keeps your greenhouse secure throughout the year.

Durable and Low Maintenance

Polycarbonate is one of the strongest greenhouse materials available.
Morrifield’s panels are:

• Impact-resistant

• Lightweight and easy to handle

• Resistant to discolouration

• Designed for long-term outdoor use

Excellent Insulation Year-Round

The twinwall design traps heat, making it easier to grow in colder months and extend your growing season.

UV Protection and Even Light

Polycarbonate blocks harmful UV rays and spreads light evenly throughout the greenhouse.
This reduces shadows and helps plants grow more uniformly.

Versatile and Cost-Effective

Our greenhouses are available in a range of lengths to suit your space and growing goals.
Polycarbonate is also more affordable and longer-lasting than glass, with fewer repairs and replacements.

Warranty and Added Protection

• 15-Year UV Warranty on polycarbonate sheeting

• 10-Year Warranty on framework and parts

• Breathable foil tape to reduce moss, mould and moisture buildup

These features help extend the life of your greenhouse and keep it performing well for years.

Important Information About Weather Exposure

Morrifield Greenhouses have been proven in New Zealand weather for over 40 years.
However, proper placement is crucial for long-term performance.

We recommend:

• Good wind shelter, especially from strong Nor’Westers or prevailing winds

• Avoiding highly exposed or funnelled wind areas

While our materials are extremely durable, we cannot guarantee against severe weather events like cyclones or tornadoes.
