JONAH Lomu maintained a determined silence last night as New Zealand arrived in the territory ready to defend their title at the Cathay Pacific HongkongBank Sevens which starts on Friday. The newly-married All Black winger, sporting a new dreadlock hairstyle, refused to talk to the media and was shielded by coach Gordon Tietjens who said his superstar would want as much privacy as possible this week. 'He has been hounded wherever he goes and there is a growing security problem. Unlike in 1994 [when he first played at the Hong Kong Sevens], he is a superstar today and this has caused problems,' said Tietjens. Lomu's 19-year-old wife Tanya Rutter would join him over the weekend according to Tietjens: 'But for the moment he is focused on the tournament and he needs all the space and time away from the public eye.' They arrived from Auckland with only seven players. All Black full-back Glen Osborne and Peter Woods are playing for Waikato in South Africa against Transvaal in a Super 12 fixture. They arrive tomorrow. Captain Eric Rush had already arrived. Tietjens refused to conform to the universally held view that New Zealand are clear favourites to win. 'I'm worried because most of the team, including Jonah, have not played sevens rugby this season,' he said. Only halfback Joe Tauiwi and forward Waisake Masirewa played at last week's Fiji Sevens where a young New Zealand side lost 22-21 to Fiji.
