embedding google map html code

Hi,

I understand how to place the html map code in the php file and show the map I want, ie home.php and paste the long code there, but what if I wanted to put that map in a post, not in pages but in posts?

<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.co.nz/maps/ms?msa=0&msid=206809597945320768203.0004d30aab2531c937494&ie=UTF8&t=m&ll=-36.878522,174.732056&spn=0.192239,0.291824&z=11&output=embed"></iframe><br /><small>View <a href="https://maps.google.co.nz/maps/ms?msa=0&msid=206809597945320768203.0004d30aab2531c937494&ie=UTF8&t=m&ll=-36.878522,174.732056&spn=0.192239,0.291824&z=11&source=embed" style="color:#0000FF;text-align:left">example</a> in a larger map</small>

so how do I show the above google map in one of my post? I tried, adding post and switch to the html editor and paste the code there but it didn’t work.

Anyone know how to embed google map html code in posts?

Thanks everyone
