Kind of. The telcos are renting capacity on the Starlink constellation to transmit their NZ licensed LTE radio spectrum, this is spectrum they would usually transmit from a terrestrial cell tower.
Specifically OneNZ took their Band3 (1800MHz) and contracted Starlink to transmit it from their satellites. SparkNZ have not published what they are using, but some sleuthing has determined it's Band 7, which is kind of odd for reasons I won't go into.
