WordPress category & taxonomy loop with pagination

Don’t use 'numberposts'=>-1 because numberposts is depracated moreover -1 shows all the post on one page.

Instead use posts_per_page and set its value according to how many posts do you want.

$paged= (get_query_var('paged' )) ? get_query_var('paged'):1; 
global $query_string;
$myquery = wp_parse_args($query_string);
$myquery = array(
    'paged' => $paged,
    'posts_per_page'=>10,
    'tax_query' => array(
        'relation' => 'OR',
        array(
            'taxonomy' => 'category',
            'terms' => array('adventure'),
            'field' => 'slug',

        ),
        array(
            'taxonomy' => 'holiday-types',
            'terms' => array('adventure'),
            'field' => 'slug',
        ),        
    ),
 );
query_posts($myquery);

while ( have_posts() ) : the_post();
    echo '<li>';
    the_title();
    echo '</li>';
endwhile;

// Reset Query
wp_pagenavi();
wp_reset_query();
