H-deficient post-AGB objects, e.g. PG1159 type star K1-16 and born-again AGB\nstar Sakurai's object, have been reported to be significantly iron-deficient.\nWe find that the iron deficiencies expected due to neutron-capture\nnucleosynthesis during either the progenitor AGB evolution and/or the neutron\nburst that occurs as a result of the rapid burning of protons during a post-AGB\nHe-flash are generally in line with observations.\n
