I did (NZ - North Shore ~3years ago). In a PPL flight test doing a FLWOP I called "go around" at 550 AGL and the flight examiner called "continue" - I think he did this because we were a bit high and it was doubtful whether we would make the field. At this point I considered the examiner was acting as PIC, so I threw on full flaps and started forward-slipping down to about 200' which got us aiming for a good point on the field. At 150 AGL I called "go around" again and started applying power - the examiner said "OK, go around" and we were away again. Then climbing through 600' the examiner pulled the throttle closed without warning and we did the engine failure on take-off drill in a similar fashion.
