Your version is grammatically correct, but it changes the meaning slightly: "He was a New Zealander who wanted more evening hours in which insects are collected" means "Er war ein Neuseeländer, der mehr Abendstunden, in denen Insekten gesammelt werden, haben wollte." This sounds a little strange, because it's like he wanted more evening hours for everyone in general to collect insects. When you use the passive you're no longer thinking about the person who is doing the thing. "He was a New Zealander who wanted more evening hours in which to collect insects" is "Er war ein Neuseeländer, der mehr Abendstunden wollte, um Insekten zu sammeln." This is more specific: He wanted these evening hours for himself, to collect insects. Does that make it clearer? Thanks for your very interesting questions!
