"I don't like racing from behind, it's harder to catch, especially on the run where there's so many fast girls," Hewitt said.
"It's not only Gwen, there's lots of Americans who are doing well and stepping up.
"I'll be trying to stay in front on the swim and getting a good start, then on the bike I'm not going to be sitting back. I'm not going to be waiting for the run - it's not going to be one of those races."
Happily for Hewitt, that strategy will be aided by a typically tough bike course in downtown Auckland, with three hills featuring on each of the five 8km laps.
"It's really tough, there's no free rides on this course," Hewitt said.
"Especially with the forecast on Sunday as well, with the rain, it's going to be even more challenging.
"But I think it's going to be good for the New Zealanders, who like the hills and are strong athletes."
Swede Lisa Norden described the bike as Jorgensen's "weak link", with the reigning world series champion finishing 12th in Auckland last year after being caught up in a crash. And Hewitt agreed that was an area where the other contenders would make their move.
"Gwen's definitely the favourite," Hewitt said. "She's won the last six races in the world triathlon series so all the pressure's on her and we just have to do our best races.
"If we're ahead after the bike, then that's better for us. She's running pretty fast at the moment."
Katie Zafere will also be one to watch, having crossed second behind Jorgensen in the season-opening sprint race in Abu Dhabi, with Lindsey Jerdonek finishing sixth and rounding out the trio of American threats heading into tomorrow's race.
Hewitt managed fifth in Abu Dhabi and, encouragingly, recorded the third-fastest split on the run, eventually crossing 39 seconds behind Jorgensen after losing too much ground earlier in the race.
"I just didn't have a great swim. I was in the main bunch so it was tough at the beginning and it was hard to get the group working.
"We didn't actually catch the front group so we didn't work that well together. And that's not a good place to be."
