I will be landing in Vic falls and starting a truck tour which goes through Zambia and back into Zimbabwe. When I call the Zimbabwe embassy in London they say I will need to get two single entry visas at the border ($50 each). They didn't want to give me any info on multiple entry visas; is it possible to get one at the port of entry?
When I landed at Vic Falls the options I was given is $30USD for single entry or $45USD for double entry. The prices were the same for the Americans, Swiss and Germans I spoke to in the queue.
A point to note, there was one immigration officer charging people for a double entry and placing a single entry visa in there passport and writing them a receipt for a double so it pays to check the visa as its going in.
According to the Zimbabwe Embassy in the US, NZ can get a multi-entry visa on arrival.
Find New Zealand on the list here.
You can find the prices here. Currently it says 95USD for a multi-entry visa.
