Welsh hopes of finding a famous victory against the All Blacks have taken a few hits with a rising injury toll ahead of their June visit.
Three frontline choices will be scrubbed with several more on a doubtful list for the three test visit from Warren Gatland's side.
Ospreys flanker Justin Tipuric is the latest casualty with doctors deciding he needed more rest from the concussion he suffered in the Six Nations.
"The specialist advice is that it is in his best interests to take his time returning," Dr Chris Towers said.
"A prolonged three-month period of recovery rules him out of the rest of the season for the Ospreys and the Wales tour to New Zealand."
