The outgoing South Down MLA confirmed his plans ahead of the deadline for nominations on Friday.
Mr Wells had previously said he was keeping his options open after being deselected as the DUP candidate for his constituency.
Mr Poots later switched from Lagan Valley to South Belfast to run as a DUP candidate after replacing party MLA Christopher Stalford following his sudden death.
Mr Wells told Belfast Live: “I’m not taking part in the election in any way, and I’m not standing as a candidate, so I have a completely blank diary.
“I’m not standing in any capacity. At the weekend I had a retirement do with my family and pictures of that appeared all over the internet.”
Mr Wells, a former Health Minister who has represented South Down in the Assembly since 1998, said he was bowing out “against my own will”.
But he added: “To be honest I’m not missing the doors and the insults and the posters being ripped down.”
Mr Wells said he would be voting in Upper Bann as he lives just within the boundary of the constituency.
He expressed his support for DUP incumbent Jonathan Buckley.
“Jonathan and I have been quite friendly. Jonathan I think has really shone as an MLA for Upper Bann,” he said.
Asked about Mr Buckley’s running mate, former Economy Minister Diane Dodds, Mr Wells at first responded: “Jonathan Buckley is an excellent candidate.”

Pressed further on his thoughts on Mrs Dodds, he added: “Diane Dodds is also a candidate for the DUP in Upper Bann and I think is worthy of a preference.”
Mr Wells added: “I will not be voting for (Ulster Unionist leader) Doug Beattie or the Alliance candidate.”
The former MLA remained tight-lipped on who he is backing in the South Down contest, saying he plans to reveal his intentions next week.
