rewriting wordpress URL

I need to redirect a page but when it's redirected I get a 404 error. I need to redirect the page: http://oceanrafting.com.au/packages/cat-packages/ to: http://oceanrafting.com.au/packages/

The page is a category under a custom post type. Tours is the custom post type, packages is one of the categories

I attempted the following redirect:

RewriteRule ^packages/cat-packages/$ /packages/ [R=301,NE,NC,L]
which works, but the gives me a 404 error. My setup Packages is set as category base in permalinks Packages is a name of a category with the slug cat-packages

This is the code I have (generated by CPT UI) which creates the custom post type

add_action( 'init', 'cptui_register_my_cpts' );
function cptui_register_my_cpts() {
$labels = array(
"name" => __( 'Tours', '' ),
"singular_name" => __( 'Tour', '' ),
);

$args = array(
"label" => __( 'Tours', '' ),
"labels" => $labels,
"description" => "",
"public" => true,
"publicly_queryable" => false,
"show_ui" => true,
"show_in_rest" => false,
"rest_base" => "",
"has_archive" => true,
"show_in_menu" => true,
"exclude_from_search" => false,
"capability_type" => "post",
"map_meta_cap" => true,
"hierarchical" => true,
"rewrite" => array( "slug" => "tours", "with_front" => true ),
"query_var" => true,

"supports" => array( "title", "editor", "thumbnail" ),
"taxonomies" => array( "category" ),
);
register_post_type( "tours", $args );

// End of cptui_register_my_cpts()
}

add_action( 'init', 'cptui_register_my_cpts_tours' );
function cptui_register_my_cpts_tours() {
$labels = array(
"name" => __( 'Tours', '' ),
"singular_name" => __( 'Tour', '' ),
);

$args = array(
"label" => __( 'Tours', '' ),
"labels" => $labels,
"description" => "",
"public" => true,
"publicly_queryable" => false,
"show_ui" => true,
"show_in_rest" => false,
"rest_base" => "",
"has_archive" => true,
"show_in_menu" => true,
"exclude_from_search" => false,
"capability_type" => "post",
"map_meta_cap" => true,
"hierarchical" => true,
"rewrite" => array( "slug" => "tours", "with_front" => true ),
"query_var" => true,

"supports" => array( "title", "editor", "thumbnail" ),
"taxonomies" => array( "category" ),
);
register_post_type( "tours", $args );

// End of cptui_register_my_cpts_tours()
}
Any help in the right direction would be greatly appreciated. I have granted support access already
