Otematata Volunteer Fire Brigade Chief Fire Officer Kevin Powell said the second fire broke out yesterday about 1pm, in "tinder dry'' conditions and was driven by a troublesome northerly wind.
Again, it was caused by farm machinery.
On Sunday 35 firefighters and two helicopters with monsoon buckets battled to subdue flames covering 25ha on the property.
Yesterday fire crews from Omarama, Otematata and a Waitaki Volunteer Rural Fire Force officer worked to put out a 400m by 50m blaze almost at the same spot as the previous day.
The fire was not a reignition of the previous day's fire, but a new fire, which took about an hour and 10 minutes to put out.
The fires were a reminder to farmers working in the incredibly dry conditions to do their work either early in the morning when dew was about or early in the evening when the temperature was cooler.
Station owner Hugh Cameron said the fires had not affected his business and there was "not too much drama''.
"We won't be doing any more work in that area until things dampen down a bit or we get more dew.''
Mr Powell said yesterday's fire was not a danger to life or property, although firefighting conditions were smoky and it was hard to see.
