New Zealand coach Joanne Williams said the match reflected the team's eighth seeding and lack of experience.
"We need more exposure at this level. We don't have enough of that. We need to get overseas and play."
Fitness was another area that needed to improve.
"But it's not just fitness, it's about learning to move around the court as well."
Williams was delighted with the improvement she's seen in Watts and the attitude of Camden Te Kani-McQueen.
"I'm really pleased with Kaitlyn. She is such a talent. She's really impressed me."
While the final is likely to be between Egypt and Malaysia, England fancy their chances of an upset after they beat the USA 2-1.
"The pressure was on us as third seeds and we knew the USA would be strong," England manager Lee Drew said.
"Marina (Stefanoni) was in great form in the individual tournament so we knew it would be a tough match."
Stefanoni showed remarkable composure for a 14-year-old when she rallied in the fifth game of her 3-2 win against Lucy Turmel.
Having won the first two games, Stefanoni eased off, allowing Turmel to level at 2-all, before she sealed the match 11-3 in the fifth.
"The Americans are very tough competitor," Drew said, "so it was going to be a challenge but that's why we are here.
"We can go into the next match against Malaysia with nothing to lose.
"I have faith that if all our players bring their 'A' games that we can do well, but Malaysia have also got players who were in good form in the individual tournament. They are class, but it's a match we want to do well in."
That tie will be at 6pm with the match between Egypt and Hong Kong-China at 2pm. Both are at Tauranga's Queen Elizabeth Youth Centre.
