Newstalk early morning news: normally starts at 6:30 but 7:00 this wk why?

As an early riser i have become accustomed to tuning in to Newstalk for their 6.30 am news and business programme. However the programme this week starts at 7 am and am wondering why the change. If it were in winter i could understand the weather might be a factor!

No change on schedule on website. Repeat of last nights sport show up to 7am. The business part came on at 7am this morning so I think main programme will start at 7.30.

I would also listen to 6.30 to 7am slot, If it moves to 7am permanenly more than likely listen to another station at 7am

Did not hear any reason why it has moved.

New summer schedule

It seems to be back to 6.30Am again in last few days.
