Sure. It's still a requirement if a parliamentary committee wants to meet that the members must be there in person. They have no ability to take part by video conference or teleconference, but the committees do make use of video conference in the way that you are now to meet with people remotely around New Zealand, which is a very small country in comparison to Canada, but still occupies quite a lot of time to travel.
It's much more rare for committees now to travel to other centres unless they receive a very large number of public submissions and would like to be seen to be taking those views on board. Otherwise, they use video conferencing extensively to reduce travel time.
Generally speaking, committees meet on the same days that the House is sitting, although not at the same time, and so the members are usually all together in Wellington, in any case.
They have to be here in person to participate, but all of the documents that members might use, particularly for committees, are available to them electronically anywhere and on any device they use, provided they have an Internet connection.
