  The Murchison Widefield Array (MWA) is a new low frequency interferometric
radio telescope, operating in the remote Murchison Radio Observatory in Western
Australia. In this paper we present the first MWA observations of the well
known radio relics in Abell 3667 (A3667) between 120 and 226 MHz. We clearly
detect the radio relics in A3667 and present flux estimates and spectral
indices for these features. The average spectral index of the north-west (NW)
and south-east (SE) relics is -0.9 +/- 0.1 between 120 and 1400 MHz. We are
able to resolve spatial variation in the spectral index of the NW relic from
-1.7 to -0.4, which is consistent with results found at higher frequencies.
