Excessive amount of calculation restricts possibility of using $k$-nearest neighbor classification algorithms. In this paper a new method of estimation of $k$-nearest neighbor type is proposed. It is based on use of blocks of observed data. It is shown that the new estimator converges in probability. Also, the method based on the new estimator provides the same probability of misclassification as the standard algorithm does. But the new method requires much less calculation.
