Maybe something like (as others have said, assuming no copy/paste errors): 
my @checks = (
 [ qw/0 agency_id agency_id / ],
 [ qw/1 advertiser advertiser / ],
 [ qw/2 compaign_id compaign_id / ],
 [ qw/3 contact_id admin_contact_id / ],
 [ qw/3 contact_id tech_contact_id / ],
);
foreach my $check (@checks){
 my( $idx, $key, $k ) = @$check;
 get_updates($objects[$idx], $key, $result_ref->{$k})
    if (defined $result_ref->{$k} && $result_ref->{$k} != 0); 
}

Update: Changed "$result_ref->{'agency_id'} != 0" to "$result_ref->{$k} != 0" to reflect OP's correction.
