Asymptotically flat wormhole solutions are found in the deformed Ho\ifmmode \checkr\else \vr\fiava-Lifshitz gravity. It turns out that higher curvature terms cannot play the role of exotic matters which are crucial to form a traversable wormhole, and external exotic sources are still needed. In particular, the exotic matter behaves like phantom energy if the Kehagias-Sfetsos vacuum is considered outside the wormhole. Interestingly, the spherically symmetric setting makes the matter and the higher curvature contribution satisfy four-dimensional conservation of energy in the covariant form.
