The 1999 NBL season was the 18th season of the National Basketball League. The 1999 season saw just nine teams compete, with Hawke's Bay joining the second-tiered Conference Basketball League (CBL) and Northland ceasing operations after four dismal seasons in the NBL. Auckland won the championship in 1999 to claim their sixth league title.[1]
