"Ponsonby have got some real quality players and are always a strong side to play against, but for us we know what's worked well for us this year," she said.
"We've got a very strong ball-carrying forward pack and have good speed on our edges – we just have to put it all together. We have to take our time and build pressure. If we can get some continuity going and do those things well and rolling it will be a good day for us."
Itunu's memories of last year's final include her team deciding to play into the wind in the first half, only for the breeze to shift to Manurewa's backs after the break, and her confidence that Ponsonby would prevail regardless of the opposition's late comeback.
"I was nervous but I had an inner peace – I thought the girls would pull through," she said.
For Marino-Tauhinu, one of two Black Ferns in the Manurewa side along with first-five Tubic, the memories centre on her pride at her team's comeback in regulation time.
"I think with 10 minutes to go and us down by two tries that people would have thought Ponsonby would walk off champions in the 80th minute, but it's like anything – it isn't over until the last whistle and I was really proud of how our girls kept going and kept at," she said.
"They've got their fair share of Black Ferns which really excites our young girls; it's awesome when you get an opportunity to play quality players like that and really measure yourself against the best to see what it takes to get there."
Ponsonby will likely make up a large proportion of the Auckland Storm which is set to be named on Monday, with Manurewa likely to contribute well to Counties-Manukau.
Counties will have their first Farah Palmer Cup pre-season next weekend and Marino-Tauhinu said the news the FPC would be fully televised this season was a huge boost to women's rugby.
"It's the start of what could be a real career option for women moving forward," she said.
While Ponsonby's season had been disrupted by Black Fern camps, Manurewa's had been similarly affected but for different reasons. "It's been a bit up and down," Marino-Tauhinu said. "We've had a few injuries, but it's like anything at Manurewa – the culture is so awesome that us girls just love it."
Ponsonby v Manurewa, kick-off 2.45pm at Western Springs Stadium on Saturday.
