It might be because it's late but I don't think I'm following. Watercare gave 24 hours notice that developments without resource consent would not be allowed to connect until 2031. But also they have capacity for 4,000 more houses, "Our current tracking of previous years - there's typically 800 connections made a year, so that's five years of connections available.".
So they have 5 years worth of connection capacity but they aren't allowing any new developments to connect? I'm really lost on what Watercare is trying to convey.
