We demonstrate that the action for the N=4 Goldstone supermultiplet with four fermions and four auxiliary components is a universal one. The remaining actions for the Goldstone supermultiplets with physical bosons are obtained from the universal one by off-shell duality transformations.9 pages, LaTeX file, PACS numbers: 11.30.Pb, 03.65.-wHigh Energy Physics - Theorytext
