On behalf of my daughter, I'm selling her Sony MHC-V44D Speaker. It's a powerful wee thing with CD player, bluetooth support, and inputs to allow you connect it to everything but the kitchen sink (unless your sink has RCA outputs, in which case go hard).
It's approximately 2 years old, is in great condition, and we still have the original manual.
She wants $350 for it, and pickup would be from West Auckland.
