A Matamata man was so tired he forgot about his dinner that he prepared and went to bed, waking up to find the house on fire.
Waikato fire safety officer Ross Fleet said the man got home late and made some toasted sandwiches.
But instead of eating them, he went to bed while they were cooking.
The man then woke to his home engulfed in flames just before 5.30am today.
The house was well involved in fire when firefighters arrived.
