${\mathrm{K}}^{+}$-nucleon phase shifts are presented in the region 600-1500 MeV/c laboratory kaon momentum. They are obtained by a single-energy phase-shift analysis for the KN $I=1\mathrm{}$ and $I=0\mathrm{}$ states using world data including recently measured $P({\mathrm{K}}^{+}\mathrm{n}\to {\mathrm{K}}^{+}\mathrm{n})$ and $P({\mathrm{K}}^{+}\mathrm{n}\to {\mathrm{K}}^0\mathrm{p})$. The result supports the resonances in the $P_{13}$ and $D_{03}$ waves. Other resonancelike structures have also been found in the $P_{11}$ and $D_{05}$ states, which could be interpreted as new candidates for $Z^{*}$ resonances. In this paper numerical phase shifts are demonstrated as well as their accuracy. These values could be used for future studies on kaon-induced nuclear reactions.
