A good chance to improve in English

Although I have been learning English for a long time, I still can't use it fluently. Last November, I gave my notice in at work as I am going to New Zealand in March this year, through a Working Holiday Visa. It's so exciting but broken English still disturbs me and I am afraid that I won't be able to get a job without a good sense of the English language but on the other aspect, I know that it's a good chance for me to improve in my English. There is motivation if you guys helping me overcome this!

Although I have been learning English for long time, i still can't use it fluently. Last November, I gave my notice at work, and I'll go to New Zealand in March this year on a Working Holiday Visa. It's so exciting, but my broken English still disturbs me. I am worried about afraid of how to get a job without a good level of sense in English. but On the other hand aspect, I know it's a good chance for me to improve in my English. I will feel more motivated if you guys help me increase my knowledge (There is motivation if you guys helping me overcome this!)
