Flynn and Brownlie have taken the places of opening batsman Rob Nicol and fast bowler Brent Arnel.
Wellington, New Zealand: New Zealand have sought to bolster their fragile batting line-up for the third Test against South Africa, recalling Daniel Flynn for his first Test in more than two years and hurrying Dean Brownlie's return from a finger injury.
Flynn and Brownlie were named in the 14-man squad for the Test that starts at Wellington's Basin Reserve on Friday, taking the places of opening batsman Rob Nicol and fast bowler Brent Arnel.
New Zealand's batsmen failed twice as South Africa won the second Test in Hamilton on Sunday by nine wickets. Vernon Philander took 10 wickets for 114 in the match as New Zealand were dismissed for 185 and 168.
In the drawn first Test at Dunedin, New Zealand made 273 and 137-2.
Nicol had scores of 6 and 19 in Dunedin and 2 and 1 in Hamilton. In 10 innings in the Twenty20, one-day international and Test series against the Proteas, the opener has reached 50 only once.
The recall of Flynn and Brownlie and the omission of Arnel, who failed to take a wicket when he made an international return in the Hamilton Test, suggests New Zealand may carry an extra batsman at the expense of a fast bowler in the third Test.
Australian-born Brownlie has been sidelined throughout the South Africa series with a broken finger and last played for New Zealand in their one-off Test against Zimbabwe in January. He has played four Tests and accumulated 268 runs at an average of 44.66 since his debut against Zimbabwe in Bulawayo in November.
He is expected to stiffen the New Zealand batting after making three half-centuries in his first six Test innings and scores of 77 not out, 42 and 56 against Australia in Australia last December.
Flynn wins his recall for his first Test since December 2009 after moderate form in New Zealand's domestic first-class competition. Flynn made scores of 113 not out and 47 and 68 and 136 in his last two first-class matches for Northern Districts.
"Daniel Flynn is having a very successful Plunket Shield with the bat for Northern and is likely to join Martin Guptill at the top of the order," national selection manager Kim Littlejohn said.
"He was part of the team in late 2009 and we are sure he will make the most of his opportunity to again represent his country."
"We are mindful that Dean Brownlie is only just making a return to competitive cricket following injury and will keep a close eye on his progress. Although he has been included in the squad, his selection for the Test will largely depend on how he pulls through the (next) match for Canterbury."
New Zealand will take a major risk if they drop a bowler for the Wellington Test, which they must win to tie the three-match series at 1-1. Chris Martin and Doug Bracewell are likely to continue to take the new ball, while Mark Gillespie will retain his place after taking 5-59 in South Africa's first innings in Hamilton.
They also have the option of young left-armer Trent Boult, who was left out of their line-up in Hamilton.
New Zealand squad: Ross Taylor (captain), Trent Boult, Doug Bracewell, Dean Brownlie, Andrew Ellis, Daniel Flynn, Mark Gillespie, Martin Guptill, Chris Martin, Brendon McCullum, Tarun Nethula, Kruger van Wyk, Daniel Vettori, Kane Williamson.
