Mumps continue to be a bane on New Zealand's Northern Tour despite Northlander Jack Goodhue recovering from the affliction.

Now impressive rookie winger Rieko Ioane is in doubt for Sunday's test against France after also contracting the illness.

Ioane did not train last week in London or attend the scratchy win over the Barbarians - instead staying in isolation at the team hotel.

Mumps is a contagious viral infection, and the All Blacks have been wary of other squad members catching it. Recovery time usually ranges from anywhere between two to three weeks.


"It's unrelated to Jack Goodhue because they haven't been in contact," All Blacks coach Steve Hansen said as the team ventured from London to Paris on the train. "It's obviously come out of Auckland somewhere. It will be touch and go. He trained this morning it will depend on how well he comes through the week we'll wait and see."

Hansen downplayed fears the virus may infect others.

"Doc has done a great job. He isolated him so no, we're not worried."

There are plenty of options for the starting left wing spot Ioane was expected to fill.

Seta Tamanivalu impressed against the Barbarians and looks set to retain the spot while both Damian McKenzie and David Havili have the ability to cover on the wing if Hansen decided to put Beauden Barrett at fullback.

Matt Duffie is also an option, though he is unlikely to get the nod.
