For context on oil supply to NZ published by the nz govt, viz the US-Iran war.
The #NZ government has committed to earmarking #oil supply for commercial truck shipping at all costs, which I guess is what diesel is.
This confusing metric is essentially "negative price". So the plummeting "number of cents down" means the price is skyrocketing.
New Zealand, relative to other countries is extremely reliant on trucking and government subsidy of shipping via highway shipping infrastructure.
