PhoneArena has posted photos of an internal raffle document at a New Zealand mobile retailer.
The doc states that the smartphone would be given to those who will get a prize.
The pics show that the contest ends April 8th. According to the site, that means the S4 would be offered in the first week of April.
To confirm this information, PhoneArena uses a second source that comes from the UK.
According to the data they obtained, the Galaxy S4 would be available between April 15 and 22.
Recent rumors state that Samsung will hold a press conference on March 22 where the handset is expected to be displayed.
