The former Black Stick star was accused of indecently assaulting young girls in Whangārei, Auckland and Coromandel between 1975 and 1983.
Eleven of the 12 jurors found him guilty on two charges, of which there was independent evidence, relating to the second of the three women. All the complainants' identities are permanently suppressed.
The second complainant said she was indecently assaulted by Parkin, then in his late 20s, at an Auckland home. On another occasion, when she was only 11, Parkin forced her to touch his erection.
She testified during Parkin's trial that she was sitting in a sleeping bag on a couch when the Olympian reached inside, under her clothes, and abused her.
The jury unanimously ruled that Parkin was not guilty on the charges relating to the two other women.
"Imprisonment is very much on the cards," Judge Ronayne told Parkin after the verdicts were read out.

An emotional victim impact statement from the second woman was read to the court today.
"When I was 11 years old, on the cusp of turning 12, you Arthur abused your role … and sexually abused me," she began.
"My parents entrusted me into your care, and I trusted you as one of the two adults in the house with me."
"You made me not only touch you but stroke you," she addressed Parkin. "I was 11, I was a child, and you were the adult."
She said Parkin had made the decision to abuse her and then "just brushed [it] off".
"Those decisions have influenced my life ever since," she said.
"Those decisions you made will continue to influence my life until the day I die."
She described her abuse as a "disease that has grown and infected my life", causing enormous damage.
"Enormous self-doubt and a belief that I didn't matter," she said. "I didn't matter, my voice didn't matter.
"Alienated, misunderstood, told I was aggressive, cold even, hard. Even my sexuality was questioned."
She said when she was giving evidence during Parkin's trial abuse survivors approached her. They were those who "were too afraid to go public, but said they were on the stand with me".
"People have approached me and said, 'now that the case is over I can move on'. Really?' Can I?"
During the second incident, she said at trial, Parkin gestured to her to come and sit on his thigh before forcing her to touch him.
"What do you do in a situation like that? I just switched off."

The woman explained during her evidence that she initially declined laying charges against Parkin because it would likely break-up the Olympian's marriage.
"In the back of my head I thought 'what happened to me wasn't as bad as what happened to other people ... Just deal with it'. I thought I should just suck it up."
However, when she did come forward with her story she said she did so to protect other children, including her daughter.
"I had a civic duty to close the loop and to speak up," she said.
"I also looked at my daughter and thought 'that was me and I can't let that happen to anyone else.'"
"If I don't, all my years of fighting ... will go to waste".
Crown prosecutor Fiona Culliney quoted a pre-sentence report which said Parkin believed his offending was not a result of sexual arousal but "a momentary lapse of reason".
"Her recollection is inaccurate from what actually happened," Parkin told the report's writer.
Judge Ronayne said Parkin's excuse was "ludicrous and untrue" and he has "no true remorse".
"I accept her evidence as to what happened as entirely truthful," the judge said.
Judge Ronayne appeared visibly disgusted by a letter of support for Parkin by Masterton District Council chief executive Pim Borren.
The letter was written under the council's letterhead.
In it, Borren said Parkin had "made a mistake many years ago and paid dearly for it".
Judge Ronayne completely disregarded Borren's words and was seemingly disturbed he used his public office to send it.

The first complainant alleged Parkin pushed his hand under her togs while at a Northland beach during the summer of 1975-76.
"He was my hero. Arthur Parkin - the great gold medallist. All the kids wanted to play hockey like him, I wanted to play hockey like him," she said during her testimony.
Parkin's defence counsel Arthur Fairley disputed all of the charges but accepted Parkin's partial admission to the fourth charge, in which Parkin had admitted he had asked the second complainant if she wanted to touch his exposed erection.
He had been one of New Zealand's most celebrated hockey players and a multiple Olympian, winning a gold medal with the men's hockey team in Montreal in 1976.
In 1990 he was also admitted to the New Zealand Sports Hall of Fame.
