Newbie question - lump sum investment

[Noyzyboy]

Hi all,

Total newbie here so please excuse any faux pas, errors, omissions etc.

I have a windfall of around $500k coming to me later this year. I'm 46 and want to invest this to create a living wage for me when I reach around 50-52. I.e. I want to be able to generate about $60k per annum of passive income without affecting the value of my initial investment. I earn about $150k per year currently and can add approx. $50k per year of cash into this investment over the next 6 years. I'm also due another $150k windfall in about 4 years. I don't own a property and am looking to travel extensively once I reach 50-52 so can handle not having a property.

Any advice would be appreciated, including experts I might be able to speak within NZ. I've done a fair bit of research but the info I've found is very US biased.

Thanks in advance, please ask if you need more info.
