Finding Balance in a Changing Energy Landscape

Recent discussions within the industry have raised questions around energy security — particularly the role of gas — and whether targeted support for some growers may be needed to maintain production.

It’s an important conversation, and one that deserves careful consideration.

Some growers have suggested that gas supply could be prioritised, or priced in a way that reflects the importance of domestic food production. On the surface, this has merit. Reliable and affordable energy is critical for greenhouse operations, especially through winter and low-light periods.

However, it also raises a broader question: how do we ensure fairness across the sector?

Growers today are operating under very different energy models. Some remain reliant on natural gas, while others have made significant investments into alternative or renewable energy systems — often without direct financial support. These decisions have not been easy, and in many cases have required substantial capital and a long-term view of sustainability.

If support mechanisms are introduced for one energy source, it is worth considering how this impacts the wider industry. Ideally, any approach should recognise the diversity of systems already in place and avoid unintentionally creating imbalances between growers.

Investment, Transition and Ongoing Uncertainty

Over recent years, many greenhouse businesses have taken steps toward decarbonisation. This includes investment in technologies such as thermal screens, heat pumps, biomass systems, and improved dehumidification strategies.

These changes are positive for the long-term resilience of the industry, but they come at a cost.

At the same time, energy pricing — particularly for natural gas — has become increasingly variable. Even among gas users, there appears to be a wide range in pricing structures for the raw product itself. This variability can make it difficult to benchmark performance or plan with confidence.

Energy is not just another input cost — it directly influences crop performance. Decisions around heating, dehumidification and CO₂ application all impact yield, quality and consistency. When energy becomes constrained or unpredictable, productivity is often the first thing affected.

A Shared Goal: Productive and Sustainable Growing

Ultimately, the industry shares a common goal: to produce high-quality, locally grown food in a way that is both economically and environmentally sustainable.

To achieve this, growers need access to reliable and reasonably priced energy, regardless of the system they operate. At the same time, continued progress toward lower-emission solutions remains important.

Rather than focusing on individual energy sources, there may be value in looking at broader, inclusive approaches that support productivity across the sector. This could include:

• Encouraging efficiency improvements across all systems
• Supporting innovation and adoption of new technologies
• Ensuring transparency and consistency in energy pricing where possible

Maintaining a level playing field will be key to ensuring confidence for future investment.

Looking Ahead

New Zealand’s greenhouse sector operates in a unique environment, balancing commercial realities with increasing expectations around sustainability.

Affordable energy and secure supply will remain central to that balance.

With the right approach, there is an opportunity to support both productivity and progress — ensuring growers can continue to supply local markets while adapting to a changing energy landscape.

The challenge now is to find solutions that work for the whole industry, providing clarity, fairness and confidence for the future.
