Source for this? One NZ D2C is currently using b3 (5 MHz @ 1800MHz) and b7 (15MHz @ 2600 MHz) - as far as I'm aware, the largest allocation used anywhere in the world for D2C - and they are also sharing some of that b7 with Spark now, too. 2degrees' Lynk service, while it hasn't launched yet, is planned to use b8 (10 MHz @ 900 MHz).

 

As far as I know One NZ has moved to L2600 entirely for Starlink using a mix of 5 MHz and 15 MHz bandwidth around 2620-2635 MHz (or 2620-2625 MHz when limited to 5 MHz). My guess is older sateliites can only do 5 Mhz and newer ones can do 15 MHz? They did 5 MHz in 1800 MHz (around 1875-1880 MHz alongside 20 MHz terrestrial 1855-1875 MHz) previously but i believe the switch to L2600 was to take advantage of the bigger bandwidth avaliable in that band. I haven't looked at it for a while however.

2degrees said in a recently recorded presentation to NZNOG that they are only doing 5 MHz of L900 via AST. Presumely 935-940 MHz as that is currently unused with 940-945 MHz being used for terrestrial LTE service.
