Swansea will travel to Cork for their Friday night Musgrave Park clash with Pool A leaders Munster with coach Alan Gaffney warning the All Whites "we are not playing anywhere our potential."
With the Celtic League still short of the halfway point of the Pool stages - three down and four to go - Munster, Neath, Glasgow Rugby and Connacht are the only ones left with 100 per cent records.
Swansea kept their quarter-final qualifying hopes alive with a home victory over Ulster and will face a Munster side missing eight players on World Cup qualifying duty in Russia.
"We are happy with our results so far and we are relaxed about the eight internationals calls - we always knew that was going to happen," said Gaffney.
"But we have plenty of improvements to make across the paddock, we are not getting the basics right and we have to work harder.
"Swansea are a very good side and it is going to be a difficult match for us. They will consider they had a disappointing run last season but with each match they play under new coach John Connolly they will get it together more and more.
"They have some fine attacking players and a strong set of forwards. They have broken their losing run and, to score four tries against Ulster, who have an impressive defence record, is good going.
"We will be missing those eight current Irish squad players and we still have three long term injuries. But it has given the chance to our youngsters and a lot of them have held their hands up and produced the goods."
Swansea captain centre Scott Gibbs (ankle) and full back Kevin Morgan (dead leg) are All Whites injury worries, General Manager Byron Mugford declaring: "The chances of either of them playing in Cork are hanging in the balance."
