Correct way to handle a private road would be to add access=private as per access=*

Changeset description is wrong - this was scrub not Forest

Comment should have been "Remove tags from outer way of multiploygon"

LINZ imports were originally discussed staring 17/08/12 on the imports list. The imports have been going on intermittently since this time as tracked through http://linz2osm.openstreetmap.org.nz/workslices/list/?ws_state=&dataset=&layer=river_cl&user=&order_by=checked_out_at
Documentation is at osm.wiki/New_Zealand_data_import_projects

Arggh, thought I'd re-connected JOSM with my interactive account. This was not an import.

Michael, LINZ importing is covered at osm.wiki/LINZ. There is nothing specific to river imports there though. I was not aware of the need for a dedicated account for import, will try and clear that up with the people overseeing the LINZ import.
Cheers, Rob.
