Three days of interviews and book-signing sessions in Christchurch and Auckland is all the time Carter has before moving to Paris for a lucrative contract at Racing Metro.
Carter will vie with Savea, Australia's David Pocock and Michael Hooper, Wales' Alun Wyn Jones and Scotland's Greig Laidlaw for rugby player of the year. He won the award in 2005 and 2012.
Carter has been in stellar form at the Rugby World Cup, earning the man of the match award in his first Cup final and last appearance for the All Blacks.
In 112 matches, the kid from Southbridge on the Canterbury Plains has scored a world record 1598 tests points.
"Probably the finest player to have played this sometimes perplexing, often glorious game," Paul Hayward wrote in England's Daily Telegraph.
Honor Carter was back in New Zealand for yesterday's final. On October 22, she tweeted: "Your resilience over 12 years of international rugby is nothing but inspirational."
Soon after yesterday's final, Carter was on the telephone to Herald columnist and author Duncan Greive, discussing the match for the final chapter of the book.
Staff from Auckland-based Upstart Press were at work yesterday, scrambling to get it out on time.
Upstart Press director Kevin Chapman said it was a fairytale end for what promised to be a very big book with a minimum initial print run of 50,000 copies.
Mr Chapman said the book would show a different side of Carter, an introspective side of a man impacted by things like all the injuries he has had.
"They will get a new appreciation of how much of a battle it is to become the best first-five the world has seen.
"He talks about growing up, he talks about Honor and his marriage, the proposal and things like that.
"[But] he is intensely private. He will talk about some things but not others."
