I've recently moved from 500/100 Fibre, to 100/20 Fibre with One NZ. It's called Fibre Starter, and only costs $65 per month with unlimited data. The 100/20 speed is more than sufficient, and in the few months since I changed I've not experienced any slow downs or issues during peak times. If looking to save $$, most people dont need 500/100 or gigabit, consider 100/20 which might be more than sufficient for what you need. Most of my speed tests perform around 110/28.
