Lee, a regular of the US PGA Tour, won the Springfield event twice before turning professional in 2009 and has financially supported the event since.
Both of last year's successful champions, Charlie Smail (+1.4) and Carmen Lim (+.5), are entered to take on the 2018 running which may provide a different challenge than traditionally seen due to the recent and expected wet weather.
Most of the tournament's 12 years have seen a baked and bouncy par 70 layout at Springfield but the recent wet weather has the course lush and playing all of its length.
There are 39 golfers with handicaps of scratch or better in the draw, including New Zealand's top ranked female amateur Ayean Cho of Sherwood Park on a stunning +6.5 handicap. Others to watch in the women's field include two-time past winner Brittany Dryland (+2.1) and Ina Yoon (+4.2).
Te Puke's Harry Hillier is the lowest men's marker on +3.4, heading a four-pronged title attack from the University of Kansas where he is based with his brother Charlie (+1.5) and fellow Jayhawks Dan Hudson (+2) and Andy Spencer (+2).
Play gets under way at Springfield Golf Club on Devon St, Rotorua, on Saturday from 7.30am. There will be 36 holes on Saturday with the final 18 scheduled for Sunday from 8am. Spectators are welcome.
