Family visit ends in England call-up for Paterson
The Auckland native was part of the set-up for the England XV's 39-29 defeat to Barbarians earlier this month, qualifying for his adopted country through his grandfather.
And, after returning to his homeland to visit relatives, Paterson has been added to the full England squad as cover ahead of the second Test against New Zealand this weekend in Dunedin.
"We wanted some second row cover and, with Michael having trained with us leading up to the Barbarians game and knowing our systems, it made sense to call on him as he was in Christchurch visiting family," said coach Stuart Lancaster.
"He trained well with us this morning and will be in contention for selection for what is an important match against the Crusaders."
England lost the first Test of the three-match series 20-15 on Saturday.
