Yes, just like in OpenBSD those things are clearly stated in the NetBSD man page for mount:
Code:
In NetBSD, a file system can only be mounted by an ordinary user who owns
the point node and has access to the special device (at least read per-
missions). Also, the vfs.generic.usermount sysctl(3) must be set to 1 to
permit file system mounting by ordinary users, see sysctl(8). Finally,
the flags nosuid and nodev must be given for non-superuser mounts.
