All below make no sense. You can get rid of them:
<meta name="head" content= "mail forward mail box virtual address mail anonymous virtual office mail forwarding mail Mail box mail box mailbox mailboxes rentals mailing holding mail boxs">
<meta name="revisit-after" content="2 days">
<meta name="coverage" content="Worldwide">
<meta name="copyright" content="Copyright 2004 - 2006">
You can keep this if you are seriously concerned about semantics:
<meta name="Author" content="Private Box New Zealand">
Another issue. I tried to click on the navigation with JavaScript disabled and nothing happened. Where is the alternative?
I saw you are not using the headers <h1>,etc properly.
In every case <h1> comes always first and only once.
You do not need this either:
<meta http-equiv="content-Language" content="en-us">
You can add your document language straight into your html tag like this: <html lang="en-us">
