As with the other pharaohs of the Fifth Dynasty, Neferirkare was the object of a funerary cult after his death.
Cylinder seals belonging to priests and priestesses serving in this cult attest his existence during the Old Kingdom period.

For example, a black steatite seal, now in the Metropolitan Museum bears the inscription "Votary of Hathor and priestess of the good god Neferirkare, beloved of the gods".
Some of these officials had roles in the cults of several kings, as well as in their sun temples.

Offerings for the funerary cult of deceased rulers were provided by dedicated agricultural estates set up during the king's reign.
A few of these are known for Neferirkare, including "The estate of Kakai (named) the i3gt of Kakai", "Strong is the power of Kakai", "The plantations of Kakai", "Nekhbet desires that Kakai lives", "Neferirkare is beloved of the ennead" and "The mansion of the Ba of Neferirkare".

Traces of the continued existence of the funerary cult of Neferirkare beyond the Old Kingdom period are scant.
A  pair of statues belonging to a certain Sekhemhotep were uncovered in Giza, one of which is inscribed with the standard Ancient Egyptian offering formula followed by "of the temple of the King of Upper and Lower Egypt, Neferirkare, true of voice".
The statues, which date to the early 12th Dynasty of the Middle Kingdom period are the only archaeological evidence that Neferirkare's funerary cult still existed or had been revived around Abusir at the time, albeit in a very limited form.
