In you case, you should not need to handle your luggage at all in Oslo.
Avinor, the Oslo Airport operator, tell us:
DOMESTIC TRANSFER
With domestic transfer, you can arrive from abroad with certain airlines and fly onward domestically without collecting your luggage. Remember to check with your airline what applies to your journey. When using our Domestic Transfer solution, only travelers with through tickets can use the solution.
If you are coming from abroad and are headed further on a domestic flight, there are different rules for transfers based on which airline you are traveling with and where you are arriving from.
In order to use domestic transfer, you must have booked a ticket with an onward connection where the entire journey is with the airlines SAS, Norwegian, Widerøe or Emirates†. Domestic transfer is open from 07:00 – 23:00 every day.
†Applies only to travel in combination with SAS or Widerøe.
If you arrive in Norway with an airline other than SAS, Norwegian, Widerøe or Emirates and are going to fly further with a domestic flight, you must go down to the arrival hall, collect and deliver any luggage, and go through the security check in the departure hall.This also applies to passengers who only travel with hand luggage.
(follows a list of airline combinations, which includes Norwegian -> Norwegian)

How to use domestic transfer
- Follow the signs marked either "transfer" or "connecting flights" when you get off the plane.
- Next to gate D2 you will find a yellow area marked "domestic transfer".
- In the same area, there is a tax-free shop where you can buy tax-free goods before going through customs.
- Scan your ticket/boarding pass at the boarding scan and proceed through customs.
- When you have passed customs, you will enter the departure hall for domestic flights. Check the information screens for which gate your next flight is departing from and then follow the signs.
This is confirmed in this video:
- Restricted domestic transfer:
- Going through customs without luggage:
At 6:53 in the video they tell us:
So, a note about the luggage. Just before passing customs or the gates there we scanned our boarding pass and as you scan your boarding pass it asks whether you have luggage or not where you reply
yes of course if you have luggage in the hold, and then a photo of your luggage comes and you just have to confirm that it's yours. Once you've confirmed it the luggage will be transferred directly to your domestic destination.
Note that this scheme was probably relatively new at the time of that video (November 2021).
In their case, they did:
- EU/Schengen arrivals
- Security
- Walk quite a bit through the Schengen departures area
- Go through customs without bags
- Domestic departures area
Your itinerary through the airport will be slightly different as you are arriving from outside Schengen and will have to go through passport control.
