when it is very hot, the roots in the pot might burn by high temperature, get the plant out and put into soil. or you can shield you pot from sunshine to cool down the root.

Hi Geoff and Domenic, I had perfectly healthy looking tomatoes before the heatwave and now have the same problem, most have developed brown lesions on the base. After googling I think it's blossom end rot caused by water stress from the heat. Can't post a link, but try googling Tomato Problem Solver to see pics.

Tony, check that your potting mix is not too soggy. Although tomatoes like plenty of water, they also need good drainage. Have you got your bag slightly raised off the ground so that excess water can drain away?

I live on the North Shore, Auckland and have done container growing for several years now, This is the third year of growing tomatoes on a large scale - predominantly determinate varieties. I source my seeds from Kings Seeds who supply a determinate variety called Sub Arctic Plenty which I have experimented with variable results. All plants raised indoors, gently hardened off then potted out into 15L tubs. I use 50/50 new compost/previously used container soil from a non-tomato pot mixed well with added slow release fertiliser and half a cup of powdered eggshell.. The top is mulched with straw and 4 marigolds to attract the bees. They also need a 5ft stake. Generally the plants like the morning and late sun and need shade from the glaring hot midday temperatures. Each year I am growing them earlier to avoid the heat of summer. The pots on the decking facing North fully exposed struggled, the pots that were shaded midday grew much better. Next year I plan to plant out in July/August and see how they get on then. They have a mild taste, personally I prefer the richer flavours of the dark toms but they are good for dehydrating. I also found that they prefer dryer soil than some of my other varieties. I liquid feed them once a week using a litre of water. Don't let them stand in trays, they need full drainage. Any run off from the trays I use on something else (the pineapple sage is very grateful). Spay every part of the plant with a brew of bicarsoda to pre-empt and control powdery mildew weekly. Please let me know if you want any other info - happy to share. Let me know how you get on.
