NZ Agronomy Society is hosting a 2-day symposium at Lincoln University 31 Aug-1 Sep 2022 (Wed – Thu),
I will be presenting on the current state of the greenhouse sector

I am very privileged to announce I will be presenting to the Agronomy Society of New Zealand’s upcoming Symposium at the end of August.  The event is being held in Christchurch at Lincoln University.  Thanks to Tomatoes NZ and the Society I will be delivering a presentation on the current situation and future opportunities in the greenhouse sector

Like most industries the vegetable greenhouse industry has shrunk in terms of businesses but increased in acreage over the past 25 years.  A lack of returns from domestic and international markets has contributed to a massive reduction to upgrade with new technology available worldwide.  Example, lighting systems are not being introduced due to high capital/op-ex costs even though the return on investment is achievable in a relatively quick time.

I will touch on the following during my presentation:


  1. Energy
  2. Labour
  3. Old Structures/recapitalisation/re-purposing
  4. Pests and Disease
  5. Border Incursions
  6. Compliance
  7. Opportunities:
