All Blacks Brodie Retallick and Julian Savea have made the International Rugby Board's Player of the Year shortlist.
Also on the list are Springboks No8 Duane Vermuelen and fullback Willie Le Roux.
Ireland first-five Jonathan Sexton rounds out the nominees.
Retallick, not available for Sunday's test against Scotland at Murrayfield due to a shoulder injury, has been a consistently high performer for the All Blacks over the past couple of years.
Savea's strike rate makes him one of the most dangerous attacking wings in world rugby.
The winner will be announced next weekend following the final round of the autumn tests in the Northern Hemisphere. The All Blacks' final test is against Wales in Cardiff.
The IRB World Rugby Player of the Year 2014 nominees were selected by the independent IRB Awards panel, chaired by Australia's Rugby World Cup 1999 winning captain John Eales.
The panel, comprising Will Greenwood, Gavin Hastings, Raphael Ibanez, Francois Pienaar, Agustin Pichot, Scott Quinnell, Tana Umaga and Paul Wallace, has deliberated on every major test played in 2014, starting with the RBS Six Nations and culminating with the November internationals.
"As always the panellists' independent deliberations have produced a worthy list of contenders among a strong field. It has been a year where we have seen a levelling in competition with an unpredictability in so many games now. With a spread of a couple of outside backs, a fly-half, a back-rower and a lock in contention it is not going to be an easy selection to determine the Player of the Year," said Eales.
In support of the initial nomination process, fans now have the chance to have their say on the shortlist via social media. The results of the public vote will be considered by the panel when finalising the winner.
Previous winners include Kieran Read, Dan Carter, Thierry Dusautoir, Shane Williams, Bryan Habana, Schalk Burger, Jonny Wilkinson and Richie McCaw with the two All Black centurions the only players to have won the award on more than one occasion.
Short-list and IRB description:
WILLIE LE ROUX (South Africa) A strong and elusive runner from fullback, Willie le Roux has started all 10 of South Africa's tests in 2014 to take his tally to 22 tests since his debut against Italy in June 2013. The 25-year-old, who has scored seven test tries, is strong under the high ball and is potentially the most exciting South Africa outside back to come on to the scene since Bryan Habana.
BRODIE RETALLICK (New Zealand) A towering presence in the lineout, Brodie Retallick's partnership with Sam Whitelock makes arguably the best second row in world rugby at present. The 23-year-old's powerful runs and work-rate across the pitch have brought him to the fore in 2014. An IRB Junior World Championship winner in 2011, Retallick has 35 tests and one try - against South Africa in the 2013 Rugby Championship - to his name.
JULIAN SAVEA (New Zealand) With a try-scoring rate that few can match, Julian Savea has inevitably drawn comparisons with legendary All Black wing Jonah Lomu this year. The 24-year-old has scored 10 tries in 2014, including a hat-trick against England in the third test in June, to take his tally to 29 tries in just 31 tests. Savea was named the IRB Junior Player of the Year in 2010 after helping New Zealand win a third successive IRB Junior World Championship title.
JONATHAN SEXTON (Ireland) The oldest of the nominees at 29, Jonathan Sexton has been the stand-out player for Ireland in 2014 as they claimed the Six Nations title, a first series win in Argentina in June and the scalp of South Africa in Dublin last weekend. His control of the game at fly-half and perfect record from the kicking tee earned the 49-test veteran the man of the match award against the Springboks.
DUANE VERMEULEN (South Africa) A classic South African number 8, Duane Vermeulen has won plaudits across the world in 2014 for his work at the breakdown, power in the tackle and his destructive ball carrying. With 26 tests to his name, the 28-year-old was named man of the man in South Africa's 27-25 victory over world champions New Zealand in October.
