"The Silver Ferns had a superb World Cup campaign and we were thrilled to be there every step of the way as the official broadcast partner in New Zealand," Stewart said.
"The passion and commitment of the team was evident to everyone who watched, and they did us all proud. We're really pleased to be able to show our support by contributing to a bonus payment for the team.
"We congratulate the Silver Ferns on their superb win, and look forward to showcasing them again on Sky during the Constellation Cup in October."
Arriving at Auckland Airport yesterday morning, Silver Ferns shooter Ameliaranne Ekenasio said while a bonus would be nice, it was part of the reality of being a Silver Fern.
"The biggest thing is you can't compare the cricketers to us," she said.
"We play for pride, pride in the fern and the black dress. That is what gets our passion burning.
"No one here plays for the money, no one ever has. How cool would it be to get a payout, but unfortunately that's not the case."
Teammate Phoenix Karaka added similar sentiments on the pay issue.
"No feeling that could ever compare to winning a World Cup. No amount of money that could make you feel how we feel right now," she said after arriving home.
"It would be awesome if we could get a bonus but if we don't we're okay with that. Because we know we worked our butts off to get this gold medal. We didn't come here for a bonus.
On Tuesday, Silver Ferns major sponsor ANZ agreed to contribute to a fund to reward the New Zealand side for their championship-winning performance following comments from prime minister Jacinda Ardern.
Pointing out the invaluable exposure that major sponsors received from the Ferns' efforts, Ardern called on sponsors to consider a payout.
"I wouldn't want to call [the sponsors] out but ultimately they're the ones that derive benefit from us being the best on the world stage," Ardern told The AM Show.
"You couldn't have watched that game and say that those players weren't deserving of recognition ... Go on, why not [give them a bonus]?"
ANZ responded to the Prime Minister's comments, saying it is happy to contribute towards a fund to provide the Ferns with a payout.
"The Silver Ferns' World Cup victory was inspirational, so we're happy to work with other key stakeholders to contribute to a fund in recognition of the team's commitment and dedication," an ANZ spokesperson said in a statement to the Herald.
"ANZ values its partnership with Netball NZ and is incredibly proud of the Silver Ferns' Netball World Cup victory.
"Over the last 10 years, through highs and lows, we have invested about $30 million to help grow the sport of netball in New Zealand across all levels of the game from grassroots to elite.
"ANZ has been supporting women's sport in New Zealand for more than 10 years and we look forward to continuing this well into the future."
Another of the Silver Ferns' major sponsors, MYOB, said player incentives are negotiated through Netball NZ and not through sponsors.
