The following link has some good info on the NVI.

NAT Virtual Interface Feature Design
The NAT Virtual Interface feature allows all NAT traffic flows on the
virtual interface, eliminating the need to specify inside and outside
domains. When a domain is specified, the translation rules are applied
either before or after route decisions depending on the traffic flow from
inside to outside or outside to inside. The translation rules are applied
only after the route decision for an NVI.
When a NAT pool is shared for translating packets from multiple networks
connected to a NAT router, an NVI is created and a static route is
configured that forwards all packets addressed to the NAT pool to the NVI.
The standard interfaces connected to various networks will be configured to
identify that the traffic originating and receiving on the interfaces needs
to be translated.

----Note NVI is not a new way of doing NAT; it's a new feature to resolve NAT restriction.
