[nznog] Who's fibre?

A new fibre install has just showed up in a shared basement riser. It's currently not connected and no-one in the building is claiming it's theirs. The only identifying mark (written in pen on electrical tape) is "VS-42xxx" (xxx are numbers). Would anyone know which fibre company tags their new installs with labels in this format? We've been told fibre would be unavailable for years at this location, so would really like to get a circuit from that cable, if I only knew who to call.... Thanks Paul Adshead
