The first part of the Interim Act relating to entry restrictions for foreign nationals out of concern for public health (external website) imply that foreigners who are not covered by the exceptions in the law or in the regulations of the law (external website) (content in link only in Norwegian) will be expelled upon entry into Norway. The law and regulations specify several exceptions for groups that can still travel to Norway. For example, most people with residence permits can now travel to Norway, and also many EU/EEA citizens.
For more information about what rules apply to different groups who wish to travel to Norway, please see Questions and answers for EU/EAA nationals and their family members and Currently not in Norway: Questions and answers for citizens of countries outside the EU/EEA.
