Indirect dark matter detection experiments aim to observe the annihilation or decay products of
dark matter. The flux of neutrinos produced by such processes in nearby dark matter containers,
such as the Sun and the Galactic Centre, could be observed in neutrino telescopes. The KM3NeT
observatory is composed of two undersea Čerenkov neutrino telescopes (ORCA and ARCA)
located offshore of France and Italy, respectively. In this work, searches for WIMP annihilations
in the Galactic Centre and the Sun with KM3NeT are presented. An unbinned likelihood method
is used to discriminate the signal originating from the Galactic Centre and the Sun from the
background in the data samples collected with early configurations of both detectors, ORCA6 and
ARCA8/19/21. No significant excess over the expected background was found when searching
for dark matter in the Galactic Centre nor the Sun, resulting in limits on the velocity-averaged
pair-annihilation cross section of WIMPs and the WIMP-nucleon scattering cross section.
