"It was a bit of a shock last night to find out all of this and we don't have a lot of information yet," Saunders said. "We hope the world championships will still go ahead. We should find out more information on Monday.
"We were pretty disappointed to miss the medal races but it was an awesome week and hopefully we can get back sailing soon."
Laser Tom Saunders and Sam Meech will be on the water tonight contesting the spoils in the double points medal race.
Saunders has been in the top three all week and goes into the medal race in third but Meech propelled himself into contention on the back of two wins and a 16th overnight and is now in fourth.
Meech was 43rd after a disastrous first day that included a black flag disqualification for being over the start line and has steadily worked his way up the fleet. He's now only six points behind Saunders, who was 14th, fifth and 23rd in the three races last night.
"I had a much better day today," Meech said. "I had a great first two races but then lost my run a bit in the last one. It's really nice to catch up after such a terrible start. I still have a chance at a medal tomorrow so I will try to put some boats between myself and the guys in front. It might be tricky, because the guys in front have been sailing really well all week.
"It's nice to have been able to chip away but I really don't want to be in the position of needing to do that again if I can help it."
Saunders has enjoyed a more consistent regatta, collecting six top-10 scores in the nine races including one race win. He still has an outside chance of winning gold but is only three points behind Olympic champion Tom Burton of Australia.
A number of sailors in the Laser fleet struggled in the changeable and wet conditions in Aarhus last night which resulted in significant gains and losses.
"It was a very tricky day with the wind up and down and plenty of rain," Saunders said. "It was a frustrating day for me - sometimes it felt like you might as well flip a coin - but I did enough to stay in medal contention so it's all to play for tomorrow.
"The points are pretty close, and I still have a chance of gold, so I will go out and try to win the race. But I will definitely have to keep an eye on what Tom and Sam are doing. Hopefully we can get two Kiwis on the podium."
Susannah Pyatt continued her run of good results in the Laser radial but narrowly missed out on the top-10 medal race. Pyatt was ninth, second and 10th in the three races overnight to finish the regatta in 11th, one point off 10th.
She finished in the top 10 in her final six races but couldn't quite overcome a slow start to the regatta.
