  We performed a systematic 6.7 GHz Class
\uppercase\expandafter{\romannumeral2} methanol maser survey using the Shanghai
Tianma Radio Telescope toward targets selected from the all-sky
\emph{Wide-Field Infrared Survey Explorer (WISE)} point catalog. In this paper,
we report the results from the survey of those at high Galactic latitudes, i.e.
$|b|>$ 2$^\circ$. Of 1473 selected \emph{WISE} point sources at high latitude,
17 point positions that were actually associated with 12 sources were detected
with maser emission, reflecting the rarity (1$-$2\%) of methanol masers in the
region away from the Galactic plane. Out of the 12 sources, 3 are detected for
the first time. The spectral energy distribution (SED) at infrared bands shows
that these new detected masers occur in the massive star forming regions.
Compared to previous detections, the methanol maser changes significantly in
both spectral profiles and flux densities. The infrared \emph{WISE} images show
that almost all of these masers are located in the positions of the bright
\emph{WISE} point sources. Compared with the methanol masers at the Galactic
plane, these high-latitude methanol masers provide good tracers for
investigating the physics and kinematics around massive young stellar objects,
because they are believed to be less affected by the surrounding cluster
environment.
