Backup lock Dominic Bird is also out of the squad for the next three weeks because of a toe injury and has been replaced by Jeremy Thrush. There is also some concern about Patrick Tuipulotu who is struggling with an ankle problem and did not play in last night's hit-out against North Harbour and Northland at Albany.
Woodcock hurt his shoulder in the latter stages of the Blues season and after a month of medical consultation, it was decided his best avenue was surgery.
Others who sat out the match last night were Ben Smith, Kieran Read, Richie McCaw, Colin Slade, Sam Whitelock, Brodie Retallick, Israel Dagg, Owen Franks, Liam Messam, Wyatt Crockett and Joe Moody.
The All Blacks romped through the first spell against Harbour to stop the scoreboard at 41-5. Northland hung tough for long periods in their 40 minutes against the All Blacks, only beaten 19-7.
Flanker Sam Cane went off early with a cut to his head and Steven Luatua suffered cramp but they were the only injuries.
Hansen was satisfied with players like Liam Squire and Shane Christie who have joined the extended squad sessions. "Some of the guys haven't played for a while and in the second half that showed and we got exactly what we needed," Hansen said.
