Not sure about night work, but for daytime work the averaging period can be extended to up to one year by agreement (Edit: And the default averaging period is six months). Also note that the averaging is based on the official working week, which to this day still runs from Monday to Saturday, i.e. six days, so anything up to 48 h/week remains fully within the 8 h/working day average.
