in average i do not know, the biggest in Norway is deeper than the biggest in NZ, which is obvious since Norway's biggest fjord is Sognefjord which is the 3 longest in the world and the second deepest.
Yes fiords are formed through wave erosion. A sea arch is also formed through wave erosion. Other things that can be formed through erosion are canyons, cliffs, and caves.
The fiords of Norway are just features of the landscape, no special admission needed. Unless you have your own boat, or fancy a long hike, you might have to pay for traveling there, but there's no admission for the fiords as such.

Fiords (fjords).
Fjords are primarily found in countries with a high latitude, such as Norway, Iceland, Canada, and Chile. They are formed by glacial erosion and are characterized by steep cliffs, narrow valleys, and deep, often navigable waterways.
Fjords are found in countries with a lot of coastline and mountainous terrain, such as Norway, Iceland, New Zealand, Chile, and Canada.
Fiords, or fjords, are primarily found in countries with rugged coastlines and glacial activity. Notable locations include Norway, which is famous for its stunning fjord landscapes, as well as New Zealand's Milford Sound, and Chile's fiords in Patagonia. Other regions with fiords include parts of Canada, particularly in British Columbia, and Alaska in the United States. These natural formations are characterized by steep cliffs and deep, narrow inlets created by glacial erosion.
