Verdonk says the New Zealanders might struggle with a number of factors.
"The food is different from Kiwi tastes with kimchi, a spiced cabbage in a multitude of preparations, being a feature of most meals. It is more a conduit for hot chili and an acquired taste. My message to the rowers would be 'go easy'.
"In addition, there are not many tall people in Korea, so finding long-enough beds and seats on transport that have leg room will become part of the 'creature comfort' discussions."
The venue is less than 200km from the North Korean border, well within missile range. North and South Korea are still technically at war; their conflict ended in a truce rather than a peace treaty 60 years ago.
A series of aggressive missives earlier this year raised safety concerns. Rowing NZ sought security advice from the Ministry of Foreign Affairs and Trade and waited for Fisa to give the okay on its event inspection before sending athletes.
"I expect the champs to conclude without any major incidents," Verdonk said. "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 have flexed its military muscle but there is too much American influence in the region for this to get far."
The New Zealand team has appreciated acclimatising almost a fortnight before the start.
In a recent dispatch, Olympic bronze medallist Peter Taylor, whose experience has been instrumental shaping the unbeaten men's lightweight four this season, said dealing with the heat has been the biggest factor.
"The temperature is right up there. I have been to a few hot countries before, like Taiwan, China and Slovenia but they came in second to what I experienced [on arrival in Korea]. This is the reason why we are one of the first teams here, to allow our bodies to adjust so we are normalised before racing."
New Zealand team members have enjoyed the odd home comfort. A roomful sat down to watch the All Blacks beat the Wallabies last weekend when coverage was discovered on a hotel television channel.
