The next shuttle water dump is scheduled for MET 7d 15h 50m, (15 Aug, 06:31 UTC). The orbiter will be in daylight over Italy. Approximately 40 minutes later from 07:11 to 07:14 UTC, observers in New Zealand might be able to see the water cloud during an evening pass, although the gibbous moon may make viewing the cloud difficult. For technical details on how a water dump is performed: http://shuttle.nasa.gov/reference/shutref/orbiter/eclss/wastewater.html Observations of some shuttle water dumps can be found at: http://www.satellite.eu.org/h2o_dump.html http://www2.plasma.mpe-garching.mpg.de/sat/h2o_dump.html (alternate) More observations are discussed at: http://shuttle.nasa.gov/sts-78/crew/questions/ques51.html http://shuttle.nasa.gov/sts-80/askmcc/answers/11_30_04_59_02.html The last two URL's answered a few questions I had; A full water dump can take almost a full orbit to accomplish, and the 'mist' will usually be seen leading the shuttle in orbit.
