How to file divorce

Hi there, Thank you for your help. I am an Indian residing in New Zealand. I got married in Dec 2021, after that me and my wife lived together at my home in India for 16 days. After that she went to UK as she had an appointment for getting Portuguese passport. She went there and her parents also lives there. I have been settled in NZ since 2016, recently got my residency in March 2022. So, I just said to them I do not want to come to UK. Since then, they are forcing me to go to UK and I am denying. At the beginning, she agreed she want to come to NZ but due to force fully restraints from her father and brother she changed the decision and she also does not want to come to NZ. We had discussion with parents and between us too. Her father is not letting her come to NZ and also she keeps changes her decision of coming and not coming to NZ. I have talked to her father let her come but he says, she will not come to NZ. There were arguments on this but there is no decision coming and I can't live like this. I even said if you did not wanted her to leave you, why you got her married? For your information, this is a arrange marriage. So I want to get separated, how can I file a divorce as I am in New Zealand, She is in UK and our marriage was registered in Diu(Gujarat)
