Bit disappointed in BNZ for changing this after saying they wouldn't change the flybuys earn rates late last year.
For those who didn't do this strategy, it was: setting your BNZ Advantage Platinum to earn flybuys points, and also your flybuys currency to fuel discounts. This used to get you a 2.5% reward rate if you filled up your car with 50L at Z/Caltex once a month.
But, this strategy is no longer that good, as of last week. It used to be $15 = 1 flybuys point, but it is now $20 = 1 flybuys point.
Now you need to spend $80 to get 3c off per litre, getting you a $1.50 discount (3c x 50L), which is now just a 1.88% reward rate even when filling up 50L.
On the face of it, this is still a better reward rate than AMEX Airpoints Platinum (1.7%) or the TSB Platinum (1.43%), but you also need to make sure your Z/Caltex station is a cheap one. If it costs 25c per litre more than an alternative station, you should probably subtract around 10% off the reward due to the higher price, which even with 50L fills makes this strategy about equal to the competitor cards.
It would only beat the AMEX card due to having a lower annual fee ($90 vs $195), but AMEX gives you a couple of lounge passes to make up for that. Then there's also the extra hassle of trying to fill up 50L in one go - going before discounts expire, taking a jerry can with you, storing it, filling it from the can later. I used to fill up 40L to avoid all that, which would get me a 2% reward rate, but now I would only get 1.5% with 40L fills. Not really worth it any more.
I think for most of us, it is time to change cards to TSB - looks like they have some really good extra insurance benefits too (cellphone, price protection, purchase protection, as well as travel), which would make the slightly lower reward rate very much worth it.

Did you apply for TSB card? How did it go with you?
I'm not an existing customer and tried to apply but seemed to have an automated rejection? Can't really recall but was told to ring the number and had no confirmation email of the application being processed/reviewed.
