  To improve the estimate of SN rates for all types as a function of redshift
has been proposed and accepted a three years SN search with the VST telescope.
To help planning an optimal strategy for the search, we have developed a
simulation tool used to predict the numbers of Supernovae of different types
which are expected to be discovered in a magnitude-limited survey. In our
simulation a most important ingredient has been the determination of the
K-correction as function of redshift for every SN types and filters set. We
estimate to discover about 300 SNe in the course of this search. This number,
above a given threshold, is constant even if the frequency of observation
increases. Moreover we find that to high redshift the infrared band become more
important.
