Peterson said international rowing body FISA will visit the venue this week.
Eric Verdonk earned a bronze medal in the single sculls for New Zealand at the 1988 Seoul Olympics. He says the city was never short of a visible military presence during that era and New Zealand athletes should not be too concerned.
"Even then we drove in buses with police escorts. In fact, the security issue didn't prey on my mind until the Games after-party. It was quite an affair in the village quadrangle. These black-suited, heavily-armed ninja soldiers suddenly abseiled down buildings and forced a closure to the party. They weren't even visible on the rooftops until the clock struck midnight. It was like we were going to turn into pumpkins.
"FISA will be checking every detail to the nth degree and [North Korea's communist ally] China is reluctant to interfere because their rowing is strong at present. These world championships will be an opportunity to showcase their sporting success, even if not too many North Koreans have taken to the oars.
"I expect the world championships to proceed as planned, unless there is a major invasion. I doubt that. South Korea dots its Is and crosses its Ts. It is highly industrialised and affluent with a lot of American business interests. North Korea might be flexing its military muscle but there is too much American influence in the region for this to get far."
The New Zealand squad leaves for Europe on June 14 for the next phase of their 2013 programme. They'll compete in regattas at Henley, Eton Dorney and Lucerne before returning home and heading to Chungju.
