"If we want to be successful then belief is what we need and we need to follow up with what we say we are going to do."
It is the first season for Rangataua at this level. They have been helped greatly by Black Ferns Sarah Goss, Kelly Brazier and Les Ketu, who will miss tomorrow's final because they are en route to the Women's Rugby World Cup in Ireland.
Pou says his team have exceeded their expectations already.
"The ladies have prepared very well and have trained hard just like every other team, and to be here at the end is great for us going forward.
"We would also like to wish our Black Ferns all the best at the Women's Rugby World Cup, but there is a job to be done here Sunday and that is our focus for now."
Waikite captain Eliza Stephens says their focus this year was to get into the top four and to get a home semifinal, which they achieved and now host the final.
"The primary focus on Sunday is to demonstrate to our rookies what it feels like to play in a final and how important culture means to our Waikite team success over the past five years.
"These newcomers will one day be tasked with carrying the strong legacy built upon team culture."
