Update that they are closing the bus terminal at Matera Centrale starting 18 July due to road work. If you are taking a bus that uses this as a destination be aware they will be using the bus stops on Via Europe - a couple blocks farther awya from the sassi.
That is correct.
Thanks Peter that's good to hear.
My ryan air flight arrived with just enough time (15min) for me to catch the bus that went directly to Matera. It dropped in a parking lot just north east of the station. It seems like many buses were dropping there. GPS: 40.667177N, 16.601980E
I'm lucky I caught the bus. Lucky since the train line is under construction and replaced with several buses. It saved me the metro ride to the train station, then the bus connection to a train to another bus connection.
