He was able, after the World Cup, to play for the Ricoh Black Rams in Japan and a repeat season there held some appeal. However that would mean a temporary fullstop, at least, on his 72-test All Black career and he was unsure whether that was his best path.
Once Sonny Bill Williams left in August for his short contract in Japan and beyond, Nonu moved back into second five-eighths and reasserted himself.
If he was to comply with residential qualifications in Japan he would need to pack up and leave after the All Blacks' final test against the Wallabies next Saturday.
There were hints he might move south to the Highlanders where All Black comrade Tony Woodcock has gone, hooker Andrew Hore lives and former test forward Brad Thorn is shifting.
Meanwhile, new Blues coach John Kirwan made his overtures.
Nonu was encouraged and concerned by both New Zealand deals and unsure whether to uproot his family again and farewell his All Black future if he journeyed to Japan.
Staying with the Blues would work and Kirwan had a bold and bright plan for the 2014 campaign. Nonu would be a cornerstone in a youthful backline with exciting talent like Baden Kerr and Charles Piutau.
However, Nonu wondered if his game would benefit more in a new franchise where he would get some respite from his long-time association with coaches such as Graham Henry and Mick Byrne. The Highlanders would be a fresh start, a chance to feel the work of Jamie Joseph with assistants Jon Preston and Scott McLeod and renew some friendships, but it was another upheaval.
