Henry said: “They (England) are obviously taking this Test match very seriously. They had their cameramen there today – unless it was one of you (television) people at the back?

“Was anyone hiding behind the fence today in camouflage taking a video of the training?

“I think they (England) are pretty switched on and keen on the game.

“You look at strengths and weaknesses of the opposition and formulate a game-plan on that. How we played against Wales and Ireland is not necessarily how we will play against England. I guess they are trying to get more information.

“I think it is not necessary is it? It’s over the top.”

Henry, who does not plan to make an official complaint, added: “I didn’t see these people. They ran away on approach. I just thought I’d mention it to you people (the media).”

When asked whether he was flattered by the attention, Henry replied: “That is not the word I’d use. It’s paranoia.”

All Blacks media manager Scott Compton explained that television crews had briefly been allowed into the training session – but that the two cameramen in question had not been lined up in the designated area and were seen filming outside the agreed time.

“When approached the two men claimed to be from news agency Reuters, but then scarpered,” said Compton.

A spokesman from Reuters said the news organisation had not sent any television cameramen to the All Blacks’ training.

There was no immediate comment from the England camp.
