The All Blacks have had a huge security fence erected around part of their training pitch after discovering on arrival that guests from their hotel's restaurant could watch every move.
The team had two "private" training sessions which were effectively open to guests at the Lensbury club, their hotel in Teddington, south west London, before Rugby World Cup organisers remedied the situation.
The temporary fence, about 4m high and which surrounds a smaller one, was the organisers' idea, said All Blacks manager Darren Shand.
"The venue requirements for all teams are clear - everyone gets the same [ability to train in private]," he said.
"When we came here on the first day with people from England Rugby, straight away we knew it was inadequate. It [is now] at a level that has always been perceived to be about right.
