If my memory serves me correctly (because I haven't been there for a while) the NIZ 'Riviera' VOR/DME 04L/R circling with prescribed tracks approach requires the procedure described by Gusting_45 above.
If there is an ILS involved, press the App Pb as soon as you can. The Airbus has been known to snap violently upwards to capture false G/s lobes.
Our 'Discontinued Approach Procedure' goes like this:
VS Push
Select Green Dot
If GS Armed, Push App Pb
Flap In 1 Stage (if appropriate)
Gear Up (if appropriate)
Use V/S and FCU Alt to achieve desired Alt
Further Flap Retraction on schedule (if appropriate)
Hope that helps. It is really designed when you are sent around from an Alt above the FCU alt in which case, if you engage TOGA, SRS will take you skywards until you intervene.
