Ross says the Port Taranaki Whio had been fantastic ambassadors of the region in their first two seasons back in the top level of women's rugby, the Farah Palmer Cup national competition.
"We've really enjoyed watching the Port Taranaki Whio get stronger and develop as a team and we want to help them build on this progress. The more our region's best players take on the best players in the country, the more the sport will grow and will give our younger female players something to aspire to."
Port Taranaki has had a long association with Taranaki Rugby, including a term as principal sponsor of the Taranaki Bulls men's team.
Ross said the company was proud to support the community and regional organisations.
"Rugby, like many sports, businesses and organisations, has had it tough in recent times. As a Taranaki company, we aim to be profitable and sustainable so that we can give back to the community, and we are very proud to be able to offer support."
Taranaki Rugby chief executive Laurence Corlett says Port Taranaki's continued backing of the women's game was much appreciated.
"Taranaki Rugby are delighted to have the support of Port Taranaki for the next year to grow girls' and women's rugby here in the region.
"We are determined to improve on the excellent work over the past few years and keep building on participation numbers in the junior grades. We also need to make sure we can improve our high performing players and push their case for higher honours."
This year, the Farah Palmer Cup will be split into North and South pools, with the Port Taranaki Whio in the North pool, along with Northland, North Harbour, Auckland, Counties Manukau, Waikato and Bay of Plenty.
The Whio's nine-week season kicks off on Sunday, August 23, with an away match against Northland.
