Norway on Tuesday announced a month-long extension to its tighter border checks for arrivals from Denmark, Germany and Sweden.
"The controls have had a good preventive effect and there are no reports that the controls have caused problems for travellers," said Anders Anundsen, minister of justice and public security.
Norway is not a member of the European Union but is part of the passport-free Schengen zone.
The border controls, which were first introduced in November, are to be extended until April 13, the ministry said.
The Norwegian Directorate of Immigration said it registered 806 asylum bids for the period January 1 to March 13, compared to over 1,100 bids in the same period last year.
The right-leaning government in December began discussing tougher asylum rules for family reunification and permanent residency. The move is part of a bid to make the country "less attractive" for those not in "real need" of protection, Sylvi Listhaug, immigration and integration minister said.
