We perform a Noether analysis for a description of translationtransformations in 4D kappa-Minkowski noncommutative spacetime which is basedon the structure of a 5D differential calculus. Taking properly into accountthe properties of the differential calculus we arrive at an explicit formulafor the conserved charges. We also propose a choice of basis for the 5Dcalculus which leads to an intuitive description of time derivatives.
