Total all industry fuel volumes down 4.78% on pcp and Z group total fuel volumes down 5.62% so we are talking < 1% market loss all inclusive. Which is largely due to Caltex petrol dropping 19.28%. Z diesel is actually up 2.63% on pcp... while again caltex diesel dropping by 7.32%. So really Caltex is the let down at the moment.
Looking at retail (typically higher margin than fuel), there is a 7.41% increase in store only transactions. This is also reflected in average weekly store sales which are up 7.88% (6.99% like for like), which across 202 stations accounts to over $600k per week increase in spending just in the shop. Seems people are still looking for service and fuel, not just unmanned stations.
I'll believe peak oil consumption in NZ when I see the evidence, one contraction does not a trend make.
