Two men accused of embarking on a two-week-long armed robbery spree in northern NSW have been caught in a motel just days after their latest robbery.

The two men, aged 24 and 34, were arrested at a motel in Adamstown on Thursday after they allegedly robbed a sandwich shop, video store, credit union, hotel and a takeaway outlet on the far north NSW coast.

The robberies occurred over a two-week period in January and February this year.

In four of the robberies the men were armed with at least one handgun, while the other involved a knife.

The latest robbery was committed on Monday.

Officers have charged the men with several counts of armed robbery and other charges relating to firearms and concealing offences.

Police say the 24-year-old man is believed to be wanted on arrest warrants in Queensland, South Australia and Western Australia.

Both men have been refused bail and will face Newcastle Local Court on Friday.
