You can use EXECUTE USING to pass NEW to it. Your example would be

EXECUTE 'INSERT INTO ' || TG_RELID || '::regclass SELECT $1' USING NEW;

(Note that I use TG_RELID casted to regclass instead of fiddling with TG_TABLE_SCHEMA and TABLE_NAME because it is easier to use, if nonstandard. But then, plpgsql is nonstandard anyway.)
