Part of the reason was the travel toll, which was a significant burden for semi-professional athletes.
But this year's scheduling means the team will spend the middle bloc of the campaign at home.
The NRL has also announced a second standalone NRLW match on Sunday, September 29 when St George Illawarra will play the Sydney Roosters at Leichhardt Oval.
The final NRLW draw and venues, including the team the Warriors will play at Mount Smart Stadium, will be released following the end of the NRL's final regular season round.
"We couldn't be more excited and honoured to host the first standalone NRLW game in history," said Warriors CEO Cameron George.
"We're immensely proud being one of the competition's foundation clubs and to now have our team playing at home for the first time is hugely significant."
After finishing third in the inaugural NRLW season, the Warriors will start their second campaign on the weekend of September 14-15, play their second match at Mount Smart Stadium on September 22 and their third and final game will be against Brisbane on September 28 (venue to be confirmed). The grand final will be played at ANZ Stadium on Sunday, October 6.
Tickets will be on sale for the Mt Smart clash from Monday, August 19.
