We are visiting New Zealand for our honeymoon in March-April. As per visa regulations, we must have 1,000 NZD in our account. The minimum visa duration is 3 months. So, should each of us have 1,000 NZD in our account or 3,000 NZD?
According to Immigration NZ, you are each expected to have access to at least NZ$1000 per month of your actual stay, or NZ$400 in the case of prepaid accommodation.
As you are staying for 15 days and this is half of a month, you will each need to have half of this amount.
Remember that this is additional to the funds required for any further travel if you have not yet purchased the exit ticket, and will barely cover the minimum needs of a traveller (i.e. food).
Therefore, you together will need a minimum total of NZ$1000 (or NZ$400 with prepaid accomodation) and should plan to have more where possible, especially if you will spend some of this money on entertainment or for other travel purposes.
