As an island nation with a complete dependence on fuel imports, what would happen to us if a global disaster cut off our fuel supply?
We have just 21 days of diesel in the country at any time, so there are major implications for our food production and supply.
However a new study published in the international journal 'Risk Analysis' suggests biofuel from locally grown canola could be an answer.
Professor Nick Wilson of the University of Otago, Wellington co-authored this study and he's with us now.
