Hi Jason,
The template is for a 'single fold' brochure, using a single sheet of paper, printed on both sides. Changing this to a four page email version is doable, but a bit tedious. You do have one advantage over a North American user trying to do the same thing—your next smaller page, A5 has the same aspect ratio as the current A4, so you won't have as much fiddling to do to make the copy and illustrations fit in the right places.
Here's the process I went through, using the "Local Caterer" template. (Mine starts out as US Letter size, so there are some proportion issues that I ignored as I wasn't going to save the finished piece.
The New document
- Open a new Blank Page layout template.
- Go File > Page Setup, and set the Paper size to A5
- Use the +Pages button to add three Blank pages to the document.
The Original document
- Open the Brochure document.
- Set the view scale to a size where you can see all of one 'page' (eg. the front cover) in the document window.
- In the View menu (or the View button) choose Show layout.
The elements of each page are a set of graphic objects and text boxes containing all of the text. On this template, each text box is independent (not linked to another text box). If yours contains linked text boxes, you may need to experiment and make some adjustments to the procedure.
In the Old document:
- Place the mouse pointer in the grey space between the A4 pages, and just to the right of the (vertical ) blue layout guide line.
- Click and hold the mouse button and drag up and right across the front cover page unntil you get to the top right corner of the page.
- Your result should resemble the image below:

- Copy.
In the New document:
- Click on the first page.
- Paste
- Use the mouse and/or the arrow keys to move the still selected objects into position.
Repeat for each of the other three pages.
Save.
Option: You may want to Group (Arrange > Group) each pages objects before copying them.
If you are preparing other brochures, you may want to save the result as a template. See Chapter 13, Designing your own Document Templates in the Pages '09 User Guide for instructions and how to prepare the document for use as a template. You can download the guide through the Help menu in Pages '09.
Regards,
Barry
