Karunki is in Tornio. You'll find Tornio online at www.tornio.fi.

At the website of the Finnish Genealogical Society, there is a searchable database containing old parish records. Tornio belongs to area 19, Lapland. And the website is worth a very good look, as it offers a treasure trove of information and advice on genealogical research in Finland, in addition to an excellent mailing list called Finngen.

Happy hunting!
