Do you actually require splitting the hash? Partitioning the keys might suffice in many situations.

In any case, using part is one option. 

use List::MoreUtils qw(part);
use constant NWAYS => 3;

my $i;
#my @AoA = part { $i++ % NWAYS } keys %hash;
my @AoH = map +{map {$_ => $hash{$_}} @$_}, part { $i++ % NWAYS } keys
+ %hash;

Update. Much cleaner with key/value slices[*] (untested): 
use 5.020;
my @AoH = map +{ %hash{@$_} }, part { $i++ % NWAYS } keys %hash;
