New Zealand's Andrew McKenzie was 10th overall after a strong start to the regatta and George Gautrey was 41st. Susannah Pyatt was the best of the Kiwis in the Laser Radial, finishing 38th, and Olivia Christie was 46th.
"I'm really happy with how the season is going so far and there's still a lot to go," Meech said.
"I feel like I'm sailing well. I'm just making a few mistakes in each regatta that the person in front of me each time didn't. I just want to be in with a chance [of winning] going into the last race, so I'm confident with my speed and tactics. It's just performing consistently that's tricky."
Meech started the week brilliantly, winning four of his six qualifying races and added another race win on the first day of gold fleet. He hit a little speed bump with a 15th and a 17th as Wearn continued to bank low scores and went into the final day needing to make up seven points on the Australian.
"We had a reasonable breeze by the time we got started and I managed to get a good start and be up there all the way around which was nice," Meech said.
"Unfortunately Matt Wearn won the race which put him a few more points in front so it was going to make it tricky [to catch him].
"Then we had a few general recalls [as we tried to start the final race] and just ran out of time with the 5pm cut off, which was a shame because it would have been nice to finish the series."
McKenzie was 15th in the final race to hold on to 10th overall but had visions of at least replicating his third place at last year's European championships after such a good start to the regatta.
The pair will now return to New Zealand to prepare for August's sailing world championships in Denmark, which is the pinnacle event of the year and the first chance to qualify the boat for the 2020 Tokyo Olympics.
