My miniature sedge is Carex berggreni Petrie, from New Zealand.

No. There is a listing in IPNI thus, and it probably concerns the same plant
(not a certainty), but it will be named after a Mr Berggren which means that
the correct spelling is Carex berggrenii (double -ii). The spelling
"berggreni" would only be acceptable if Berggren is a mountain, an island or
a lake, or something like that.
