The former Poverty Bay-East Coast representative had a 1-up lead at several stages in the front nine, including chipping in for birdie-2 on the fifth hole.
But when Reynolds made a par from nowhere to square the match on the eighth, Atkins never got in front again.
He certainly tried, winning the 11th to square the match after trailing 1-down at the turn.
Wins on the 12th and 13th holes, however, put Reynolds and Leggett 2-up, and when Reynolds parred to win the 15th, Atkins was staring down the barrel at dormie-3 down.
Leggett inflicted the killer blow on the 16th but both winners had plenty of praise for their vanquished opponent, who was 4-over the card when they shook hands.
The Te Kanawa Cup has a rich history dating back to the former Turanganui Golf Club.
Reynolds and Leggett joined a prestigious group of multiple winners — Leggett having won it with Stu Blair in 2009; Reynolds with his “poppa” Allan Nairne in 2015.
Nairne’s name features on the trophy more than any other club member — five times.
“After we won on 16 he gave me a hug and told me I’m still three away from him,” said Reynolds.
“I knew that damn well and plan on beating that record.”
With Leggett, of course.
