Just got the following email from One NZ
Important: Your broadband price is increasing
Kia ora
At One New Zealand, we remain absolutely focused on keeping you connected, giving you great value and continuously improving the service you receive – and we’ll always try to offer you the most competitive prices.
But third-party companies who charge us for connecting to their network to provide your broadband service have increased their prices once again. With other business costs also on the rise, unfortunately we need to increase the price of your broadband.What does this mean for you?
From 2 October 2023, your Unlimited Fibre Max broadband plan will increase by $6 a month. This will not affect any Pay Monthly mobile discount you have, your access to One NZ Rewards, or your SuperWifi (if you have it).
I've recently signed a 2-year contract with them, in return for a $200 account credit.
Does this mean I will need to suck this up, or would I have an option to change to a cheaper provider?
Keen on hearing other Cheapies comments :)

I'm actually surprised that they are changing the prices on a customer that signed up for a fixed term, but this is VodafONE I guess.
If you get to keep the $200 and can exit for free, then it seems very positive for you.
