I imagine them to be concentrated in the far east of the Hither Lands, along the shores and in the south east, in ancient Hildorien, where tradition and lore are firmly rooted in the narrative that holds against the renegade Valar and his accomplices who attempted to ruled Middle-Earth. I figure the coming of the Istari would have been most succesful there. I am inclined to assume the two Istari would have directly aimed to go there and to the Avari heartlands, which were probably in the Taur Romen (a.k.a. Eryn Rhûn), the area of Cuiviénen and the wild woods of the Hither Lands. Overall the entire far east would provide safe havens for many good aligned peoples (with dwarves along the spine of the east, the Orocarni, men along the shores and elves in the woods in between). Only the Avari would have relatively easy access to (secret) routes that connected their folk to their kin in the west, following the many desolate patches of woods scattered over the Palisor and connecting them to the Taur Romen and Dorwinion.
