The All Blacks are the only side Ireland have never beaten but they will be targetting a landmark victory when the Kiwis visit the Aviva Stadium on Saturday
To date in the Autumn Series Ireland went down to a narrow 23-21 defeat to the Lions' last opponents, South Africa. They then recorded a unconvincing 20-10 victory over Samoa.
But Fitzgerald insists Ireland are still confident ahead of taking on the Tri-Nations champions.
"I think everyone is confident and I'm confident that whatever team takes the field on Saturday will be able to do a good job for us," said Fitzgerald.
"Personally I feel very confident. Within the squad I don't think there is any sign of anyone lacking in confidence.
"I think everyone is very confident. Maybe the spectacle hasn't been there in some of the games, but I don't think either team have played well in the two games. We know there are areas where we need to improve but I think we are going in the right direction.
"I don't want to give an excuse for it but I think the conditions don't really suit that expansive rugby. Everyone is itching to get their hands on the ball constantly. I think it's just a matter of doing it at the right times.
"I've only ever played New Zealand once. I'm not bringing too much baggage myself, I don't really think about the record that much. I don't think it will have much of an effect on the team."
