Is it necessary to show income in bank statements for agricultural income in New Zealand?

Yes, for a New Zealand visa, you must show that agricultural (farming) income is directly linked to you. Income only in your father's bank account is usually not sufficient.

Provide bank statements in your name showing the farming income, along with supporting documents such as business registration, tax returns, and invoices. This helps prove the income is genuinely yours and meets the visa's financial requirements.
