Understanding the consequences of the E_{7(7)} duality on the UV properties
of N=8 supergravity requires unravelling when and how duality-covariant actions
can be constructed so as to accommodate duality-invariant counter-terms. For
non-supersymmetric abelian gauge theories exhibiting U(1)-duality, with and
without derivative couplings, it was shown that such a covariant construction
is always possible. In this paper we describe a similar procedure for the
construction of covariant non-linear deformations of U(1)-duality invariant
theories in the presence of rigid N=2 supersymmetry. This is a concrete step
towards studying the interplay of duality and extended supersymmetry.
