Nefertem did not have a consort or wife.
Most often Nefertem is shown with a lotus flower somewhere upon his person, but you would have to attach the exact image of Nefertem to this question to be sure.
Perhaps two; Maahes and Nefertem by Ptah.
The ancinet Egyptian god Ptah and goddess Sekhmet.
Sekhmet is thought to be the consort-wife of Ptah and mother of Nefertem.
Sekhmet's father is Ra, her consort is Ptah. As a apect of Bast, she is thought to be mother of Maahes; her son was also Nefertem.
Ptah was her consort, Ra her father and her sons are Nefertem and sometimes Maahes.
There are different accounts on this so it is not certain, but Khonsu, Nefertem and Maahes are mentioned as children of Bastet.
Nefertem and Maahes are called the sons of Bastet, but they are not noted in Egyptian myth for having any children of thier own.
Egyptian deities (ntr) were often placed in triads and family groups. The wife of Ptah was Sekhmet (or alternately Bastet), and their child was Nefertem. They were primarily worshipped in the city of Memphis.
Bastet was identified with Hathor, Mut, Sekhmet, Tefnut; she was the daughter of Atum/Ra and soemtimes Isis; her consort was Ptah, she was also said to be mother of Anubis, or Mahes and Nefertem.
The Memphite Triad consists of Ptah, the creator/sun god, Sekhmet, feline-headed goddess of war and medicine, and Nefertem, their son the god of lotus and fragrance. Sekhmet was often seen as the guardian of the Egyptian people, the worshipers of the sun god but ferocious to those who rebel against the sun god. Ptah was said to have fasten the world from chaos. Nefertem is often shown as handing a deceased person a lotus flower, which were sniffed for rebirth in the afterlife.
Nefertem's arrival on the mythological landscape coincides with the very beginnings of the world. In this particular creation myth (and Egyptian mythology possesses several versions of the origins of Earth and humans), a giant spectacular lotus emerges to float alone upon the primordial waters of Nun. On the day of creation, the lotus opens to reveal a beautiful male child nestled in the center. The baby boy's tears produce humanity. This baby, identified with Nefertem, ultimately matures into Re.
