A multi-zone, one trip completion system for a wellbore is described. A plurality of isolation packers is installed in borehole to isolate a plurality of zones of the annulus between a tubing string and a wellbore. Each tubing string section is positioned in a zone and comprises a selectively openable stimulation port to provide stimulation fluid to its zone and a selectively openable production port to receive fluid from its zone. The system also comprises a circulation system with a plurality of circulation tubes and circulation tube valves, being configurable in a plurality of configurations to selectively connect, via a circulation flow path, the central bore or the borehole annulus of a wellbore at each of the plurality of sections, to an upper circulation flow path open to an annulus above an uppermost of the plurality of isolation packers.
