Nonu and loose forward Jarrad Hoeata took no part in the match because of bans for transgressions a week earlier against the Crusaders. The regular yellow cards incurred by Highlanders players shows they have the worst discipline of any team in the competition, another black mark against Joseph.
All Blacks midfielder Nonu, a prized signing from the Blues, has been underwhelming for the Highlanders, appearing to save his best for the national team. Returning from the June tests, he was left on the reserves bench by Joseph before his moment-of-madness tip-tackle on the Crusaders' Tom Marshall.
Nonu, off contract at the end of the year, has been unavailable for comment but his relationship with Joseph is now thought to be frosty at best.
It is unlikely to get any easier for Joseph next year. Amid rumours of over-training and other "old-school" techniques, a host of players are leaving the franchise, including Colin Slade, Hosea Gear, Kade Poki, Jamie Mackintosh and Tamati Ellison.
The exit of loosehead prop Mackintosh for the Chiefs has angered many in the deep south as the Southland skipper is one of the few born and bred in the catchment area. Mackintosh was the Highlanders' captain last season but has been on the outer since Woodcock's arrival.
Many who have the option of leaving are taking it - the exception being fullback Ben Smith who has signed a new contract to remain.
Even without his cast-iron contract, Joseph was an unlikely candidate for the axe, however. The lack of alternatives for the post has strengthened his case, even if the Highlanders have gone on a downward spiral under his command.
Eighth in his first year, the Highlanders finished ninth last year.
This year the best they can hope for is 12th, providing they beat the Rebels.
