"Conrad is a good barometer and we may well do something for Conrad before his career ends as well, given his longevity and loyalty. We did discuss the number of tests that we'll play next year at the board meeting and we've got some discussions to have with parties on the other side of the world before we make that public."
The All Blacks are slated to play Ireland, France and England in the Northern Hemisphere next season and are understood to have an option of adding a test against Wales or an international against the Barbarians as a money spinner.
However, given the NZRU's improved financial situation since the AIG jersey deal, which is locked in until 2017, and the poor performances by the All Blacks in the "add-on" revenue-gathering tests against the Wallabies in Brisbane (an 18-18 draw) and defeat by England, an extra test at the end of the year looks unlikely.
"Now that we've locked in a considerable proportion of our commercial revenue we can make our decisions based on what's best for the team rather than necessarily having to take the money thing into account," Tew said.
Captain Richie McCaw's sabbatical will rule him out of the game until after the June tests against France, and Keven Mealamu ruled himself out of the Blues captaincy in order to start Sir John Kirwan's first season at the franchise late.
McCaw has also negotiated several previous late starts at the Crusaders, with Blues prop Tony Woodcock activating that clause in his contract this year.
Who's due for a break?
Conrad Smith (Hurricanes), age 31, tests 66
Yet to have a sabbatical, Hurricanes skipper Smith is a defensive linchpin who looked weary against England.
Kieran Read (Crusaders), age 27, tests 48
Read will captain his franchise and country in the absence of Richie McCaw. Will need a break before 2015.
Dan Carter (Crusaders), age 30, tests 94
His first sabbatical in Perpignan ended in injury. Will need another if he is to play in his first World Cup final.
Ma'a Nonu (Highlanders), age 30, tests 76
Went from winning the World Cup to playing in Japan. In absence of SBW, Nonu is easily the best No12 in the country.
