I am a travel agent. Although not the one who sold OP his ticket. I hope:-) But NZ do offer routings to NZ from Scandinavia that route via the US, including SFO. So i assume it is ticketed by NZ and not SK.
But according to my GDS then, as others have written, the MCT for that connection is 105minutes. The OP has 110minutes. So not an illegal connection, although very tight
.
NZ has a description of the transfer process here
SFO Arrivals - Airport Maps, Transfers | Air New Zealand. Although it matches what others have written I thought it might be nice to have.
If you cant find a NZ ticketing booth /transfer desk open if you misconnect, you can call them on
+1 800-262-1234 which, according to my information is a 24/7 number.
