Z have lost a lot of market share recently, and are still continuing to do so. Across both brands (Caltex + Z) however Z Energy are relatively stable. Their strategy right now seems to be to pitch Z at the top of the market with high pricing and minimal discounting - they haven't run an Airpoints discount for months and have only recently reintroduced FlyBuys discounts as even FlyBuys customers were walking away from them. They're making very, very good money from this because there are plenty of people out there who seem willing to pay significantly more for petrol for absolutely no benefit....
Z's market share will continue to drop whilst they persevere with 91 and 95 petrol, that rules out high compression engines, high pressure turbos, basically, anything with a bit of oomph. They are restricting their market to your suzuki swift/Toyota Corolla/ Mazda 6 drivers. I contacted both Caltex and Z about this and they said they didn't see a need for it with the NZ fleet as it is still predominantly a japanese fleet that is safe to run on lower grade fuel. Which is bogswallop, sure smaller engined cars may be ok on 91, but I bet at 150,000kms those engines won't look as good as the same car run on 95, and I wouldn't want to run a 2L jappa on 91 either. Mind you, the way people drive perhaps it makes no difference if they think that 3000rpm is a little bit dangerous, they are causing more harm to the engine by not stretching its legs than 91 fuel is I guess.
But you just need to look at the amount of euro boxes on the road, more and more with turbos, HSVs, FPV etc, that are immediately eliminated from Caltex and Z's client base, I don't know the percentage, but I bet its a decent amount they are not able to cater to.
