  We have studied elliptic flow ($v_{2}$) of $\phi$-mesons in the framework of
a multi phase transport (AMPT) model at LHC energy. In the realms of AMPT model
we observe $\phi$-mesons at intermediate transverse momentum ($p_{T}$) deviate
from the previously observed (at RHIC) particle type grouping of $v_{2}$
according to the number of quark content i.e, baryons and mesons. Recent
results from the ALICE Collaboration have shown that $\phi$-meson and proton
$v_{2}$ has a similar trend, possibly indicating that particle type grouping
might be due to the mass of the particles and not the quark content. A stronger
radial boost at LHC compared to RHIC seems to offer a consistent explanation to
such observation. However, recalling that $\phi$-mesons decouple from the
hadronic medium before additional radial flow is build-up in the hadronic
phase, similar pattern in $\phi$-meson and proton $v_{2}$ may not be due to
radial flow alone.
  Our study reveals that models incorporating $\phi$-meson production from
$K\bar{K}$ fusion in the hadronic rescattering phase also predict a comparable
magnitude of $\phi$-meson and proton $v_{2}$ particularly in the intermediate
region of $p_{T}$. Whereas, $v_{2}$ of $\phi$-mesons created in the partonic
phase is in agreement with quark-coalescence motivated baryon-meson grouping of
hadron $v_{2}$. This observation seems to provide a plausible alternative
interpretation for the apparent mass-like behaviour of $\phi$-meson $v_{2}$. We
have also observed a violation of hydrodynamical mass ordering between proton
and $\phi$-meson $v_{2}$ further supporting that $\phi$-mesons are negligibly
affected by the collective radial flow in the hadronic phase due to the small
in-medium hadronic interaction cross sections.
