"We have never had a problem with finding teams to play us, that has never been the problem. There are teams out there who want to play.
"There is a Fifa window in March and still we don't know who we are playing so we can't plan, we can't prepare. Our players have nothing to commit to at the moment.
"If you're not playing games while other teams are playing games then yea, you're going backwards. We can't escape this. There's no magic wand. The only way to develop your team is to play games."
Hudson also attacked the culture of football in New Zealand.
"This is the second Christmas I've been here and I just don't understand how the whole of the footballing world shuts down, I don't get it. We don't play games then we completely shut down while all our competitors are in competition. It's such a casual laid back environment that colours everything we do. There's no accountability in anything that we do here. When I sit with players over the Christmas period and they're more interested in having a couple of days down at the beach, when they're overweight, they're not sharp, but trying to get professional contracts. It's delusional.
"There's no point in me being here if I don't speak about this. It got to boiling point over Christmas when I was speaking to players."
Hudson, who also oversees the national under-23, under-20 and under-17 men's programmes, said the laid-back culture of the game in New Zealand is directly contributing to the countries top footballers falling short of their potential.
"The way we're living and working is so far removed from the realities of where we need to be as young players to make it as footballers. It's delusional. And worse still, which makes the players worse, we have parents and people around these players that add to the problem by telling them how good they are. There's zero accountability with the players and they are simply not prepared when they head overseas."
The All Whites have played six games under Hudson's guidance, losing to Uzbekistan, Thailand and South Korea, drawing with Myanmar and China and, most recently, beating Oman.
"When I came in I had to rebuild the team. We've had so many debutants, 15 or 16 debutants and it's really not good, it's not right, it's far too many in six games but that's just a reflection of where we are.
"We've had the ineligibility case which has affected eight or nine players which people don't realise, we've had injuries. As of today I'm yet to name the same team twice.
"This group of players keeps me hopeful and hanging on really, but it's challenging. I'm here to coach and we want games and we have an ambition to go to the World Cup but it's difficult because we don't have a programme at the moment."
New Zealand Football chief executive Andy Martin was on holiday and could not be reached for comment.
