Photography and photoprocessing? I hate to be the bearer of bad news, but you will not have quality of life here in Argentina. You will be competing with people who are willing to work for peanuts in a country with a fairly skilled population and high unemployment. And, you will be a non-native spanish speaker and an evil foreigner.
Even if you get a job and a salary every single day your money will go less far due to inflation. If you have any expenses in NZ that you hope to pay from your AR salary it almost certainly will not work as relative to the value of the NZD you will be paid less and less as each days go by. At some point, you may not even be able to convert your pesos to NZD even if they still had some value.
Sometimes people who grow up in great privilege like someone from NZ cannot understand what the real world is like, but I assure you that unless your "love" is part of the wealth class of Argentina, then you will be coming to AR and face a very rude awakening about life. I recommend to stay in NZ and enjoy the good life.
