When preliminary nibbana with substrate occurs (that is, nibbana of a living being), constructive consciousness, that is, the house-builder, is completely destroyed and no new formations will be constructed.
However, sankharas in the sense of constructed consciousness, which exists as a 'karmically-resultant-consciousness' (vipāka viññāna), continue to exist.
Each liberated individual produces no new karma, but preserves a particular individual personality which is the result of the traces of his or her karmic heritage. The very fact that there is a psycho-physical substrate during the remainder of an arahant's lifetime shows the continuing effect of karma.
