A minor thing, Series 6 of The Brokenwood Mysteries looks to have started off with "The Power Of Steam" scheduled for 9Gem, 8:30pm, Sun, 7 June. I have it in my Manage Series list, but for those who don't, I don't recall having seen it in New Series i.e. no yellow star against the listing in My Week.
If the whole series is broadcast there will be four episodes.
