If you have warnings on, Perl will whine if it's not.

This is perfect. The input is coming from a CPAN module so I'm fairly
confident that the number of entries will be even, but checking is
always a good idea.
You may want to check first that the list has an even number of entries:
die "Invalid parameters" if @_ % 2;
but after that it's just

$_[0] is 'key', so this will assign %new_hash = ( key => undef );

I have a subroutine that will receive parameters as follows:
key1, value1, key2, value2, key3, value3, ... keyN, valueN
I want to create a hash of key1 => value1, key2 => value2, ... , keyN =>
valueN in the subroutine. I'm curious if there's a Perl "trick" to
doing this beyond the obvious loop
