This map shows the Australia-Antarctic Ridge. Australia moved almost due north from Antarctica.

New Zealand's story is far more complex. New Zealand would be a respectable continent if it were above sea level. The Lord Howe Rise, the submerged northern extension of New Zealand, doesn't fit the east coast of Australia at all. It is no doubt a mosaic of small plates that shifted as New Zealand and Australia split apart.  New Zealand is split by the Alpine Fault, a transform fault between the Australian and Pacific Plates. The block southeast of the Alpine Fault, consisting of most of the South Island (Middle Earth) and the submerged Chatham Rise, can only be fit to Antarctica by rotating 90 degrees.
