"This situation about the selection, I just don't get it," said Hudson. "I don't understand how we are compared to a club team, do you know what I mean?
"We've had people making comments [about] players getting playing time at club teams and all this kind of thing. It's just bizarre to me."
Rufer hasn't appeared in the A League since early November, when he got four minutes at the end of a 2-0 win over the Central Coast Mariners, but that was irrelevant for Hudson.
"To compare us to the Phoenix, we're completely different," said Hudson. "We have a different selection policy, we are only allowed to pick Kiwi players.
"We have a completely different style of play, we train differently, we work differently, we have longer periods in between games [and] we are on a different run than the Phoenix. I would never be influenced by decisions at the Phoenix."
His words hint at a disconnect between the Wellington club and the national body, which surely needs to be repaired ahead of a huge six months for football in this country.
However, aside from Hudson's disquiet, the omens are good for the Fiji matches. Most of the starting XI have been in great form for their clubs, and the likes of Chris Wood and Marco Rojas will provide plenty of attacking threat.
Tommy Smith and Themi Tzimopoulos will anchor a strong central defence, although it's uncertain who will form the midfield shield in front of them, with questions over Michael McGlinchey (injury) and Bill Tuiloma (form).
Ryan Thomas looks unlikely to start on Saturday, as the PEC Zwolle winger only arrived in camp on Wednesday night.
The All Whites need four points from the two matches to assure their progress to the next stage, the two-legged Oceania final to be staged in August.
