Carpets would be the preferred choice over tiles.

New Zealand! You live in paradise! Porch paint is specially made paint for wooden porches or decks. Its not a stain but an actual hard wearing & weather resistant paint that allows the wood texture to show through. Its safe for indoor or outdoor use. It is self priming & self sealing. I have used porch paint for wood paneling & kitchen cabinets & when remodeling a staircase formerly covered with carpet. It comes oil based or water based acrylic. I prefer oil based for a glossy easy to clean finish for a wooden table top. You may check your local home improvement/hardware store or paint store. I use Glidden Porch Paint. Takes me only 2 coats for white & the oil based goes on easily with a roller. Dries quickly too. Good luck!

Also take a look at Room and Board....they have several tables with different wood finishes or wood/steel/metal bases and a good selection of various tabletop materials. Also if you prefer a wood table, an area rug underneath the table could also help to break up all of the wood too.

Thank you for your comments. I really appreciate your help. I think we are on the same track. The rugs I have brought home have fought with the terracotta colour plus the busyness of the small tiles. I did come across this picture on Houzz, which I think looks good. What do you think? It would need some of that burnt orange from the chair upholstery as well as the aubergine to tie in but I liked the dark border line, it matched with the grout.
