"She does a lot for us and is always there is help," says captain Kayla Sharland.
"Debbie is like 'camp mum'," agrees Stacey Michelsen. "She is very good to us and spoils us really; especially when it comes to finding the food we like."
Balme took on the role five years ago and has faced many challenges in that time, especially as hockey adheres to a strict budget on every overseas trip.
"Our philosophy is that if we can limit costs on meals, laundry and other things, we can put that money towards bringing another player on the tour or buying some equipment," says Balme.
It has led to some interesting situations over time. The strictly Muslim nation of Azerbaijan for the Champions Challenge in 2007 brought the biggest challenges.
"Over there, women don't have any say," remembers Balme. "There we were, a group of 20 females and we weren't allowed to do anything for ourselves. Eventually we got together with the [United States] and English teams and insisted that things had to change. I don't think they knew what had hit them."
Meal times on tour can create the biggest scenes, with the players filing into Balme's room to assemble lunches (and sometimes breakfast) from the supplies laid out across the bed and desk. After arriving back from their 6-4 loss to South Korea on Friday, the team gathered in Balme's room to refuel and reflect on the loss with toasted sandwiches, complete with Watties spaghetti carried from New Zealand.
"The food can be quite different in each country but our girls like to stick to the basics," says Balme. "That is why we do all of our own shopping. In Europe, they often serve hot meals in the middle of the day [at tournaments] but 90 per cent of our players prefer something light before matches."
Over the next few weeks Argentina will present its own challenges. Most shops and business close for a few hours during the day as locals take a siesta, temperatures will hit 30 degrees Celsius and above even in the evening and the journey from hotel to stadium can take over an hour.
Some matches at the Champions Trophy won't start until 10pm, usually bed time on other tours, while 'Hola, como estas?' is the limit for most of the New Zealand group in terms of Spanish language ability.
"It has been a lot easier than I thought it would be," says Balme. "Our liaison officers are fantastic and the locals treat the team like superstars."
For now, Balme is focused on the day-to-day realities of life on tour: "We have 18-20 females so there are going to be some issues but this group is pretty good," says Balme. "Sometimes there is a boyfriend problem or other things that just don't need to involve Mark [Hager] - he has enough on his plate. A long time ago, I realised I would never represent New Zealand as a player but this job is the ultimate as far as management goes."
