Is it time for our own research facility?
It is long overdue
Holland has Wageningen University, Australia has Western Sydney University. Both of these universities have high tech modern greenhouse structures, researching protective cropping methods. The leading and most well-known is Wageningen University, that researches multiple cultivars using different scenarios, from cultivation methods, heating requirements, artificial lighting and everything to do with irrigation, the list goes on. You name it and I believe they are researching it.
Research at New Zealand universities and other tertiary institutions (in regards to food production systems) is predominantly concentrated on agriculture and arable crops. I am not aware of many collaborative research institutions in NZ concentrating on protected cropping. Several universities/technical institutions have out of date structures, which I doubt are keeping abreast with worldwide research facilities.
I believe it is time New Zealand had its very own protected cropping – high tech research facility to investigate the feasibility of growing techniques and cultivars that could provide profitability and improve New Zealand’s food security. It could also help prove what not to grow. Currently we are heavily dependent on the entrepreneurs to ‘take a punt’.
Why is it time?

As the cost of shipping sky rockets food increases at the shops, surely what covid has taught us is that we are too heavily dependent on importing certain food. We have what appears limited food security. This does seem rather ridiculous considering New Zealand exports huge volumes of fresh and processed food every day and we have some of the best growing conditions on the planet.
Examples of food imports I believe we could grow in larger volumes during the winter are berry fruit and some tropical fruit. There is the available technology to grow strawberries all year round, it will come down to the cost to invest in high tech structures and the cost of the energy. Bananas could be grown in cost effective tunnel houses in the warmest parts of NZ. However, all of these ideas require full business case studies to prove they are commercially viable. Without understanding (researching) the growing systems required including: varieties, plants per ha, production volumes etc, then producing a feasibility/business case is reliant on overseas information that may or may not relate to NZ’s climate.
New Zealand relies on exporting our horticulture and agriculture products and this will keep growing, container ships will continue to bring goods to New Zealand and be backloaded with what we do best. International trade is not going to stop if NZ reduces the amount of food we import. I sincerely believe there are huge possibilities to commercially and profitably grow a huge array of greenhouse crops in the future – we just need proof to provide assurance to business. I would fully support a NZ university to examine the possibilities and opportunity.
