Hohaia, 28, is a new face in Royce Simmons’ squad this season, which has managed just two wins and a draw from their first five Super League outings.
The New Zealand international said: “We’ve played well in parts over our last three games but I don’t think our form has been great all year.
“We didn’t play well in our trial game either. Perhaps there are a few doubts after the Grand Final? Five losses in five years can be tough to get over mentally.”
St Helens won their opening two games against London and Salford, before drawing at Hull KR. The dramatic home defeat to Catalan followed, and they were involved in another close one last weekend, going down 17-16 at Huddersfield.
Hohaia added: “One thing I have noticed about St Helens is that we are expected to win every week – and that’s a pressure everyone has – and rightly so. We have a great squad here. We are only five games into the season but we know we need to string some performances together.”
