title: Regex not detect for htaccess Redirect
body: <p>I'm looking for essentially the opposite of this ... </p>
  
  <pre><code>^(.*)(?=\/nz\/)(.*)$
  </code></pre>
  
  <p>for some reason </p>
  
  <pre><code>^(.*)(?!=\/nz\/)(.*)$
  </code></pre>
  
  <p>is not working as I thought it would. I expected it to select like this</p>
  
  <pre><code>https://www.awebsite.com/fg/about-us/our-business -yes
  https://www.awebsite.com/xx/about-us/our-business -yes
  https://www.awebsite.com/pp/about-us/our-business -yes
  https://www.awebsite.com/nz/about-us/our-business -no
  /xx/about-us/our-business -yes
  /pp/about-us/our-business -yes
  /fg/about-us/our-business -yes
  /nz/about-us/our-business -no
  /about-us/our-business - no (is this also possible with 1 regex statement or do i need multiple rewritecond statements)
  </code></pre>
  
  <p>Any guidance on getting a solution that selects all lines that don't have /nz/ in them would be much appreciated.</p>
  
  <p><em>Side-note: this is for a rewrite/redirect in .htaccess.</em></p>
