In the 2020-21 financial year it filed applications to sell 16 properties. The owners of eight of those have paid in full.
One has been sold, another four are due to be sold and a further three are waiting for the six-month statutory period to be over before they can be sold.
Some of the sales are joint efforts, with other local councils. Selling a property because of unpaid rates is a long process, and the owners can intervene to stop it at any stage.
When rates are unpaid, Horizons first lodges the matter with Debt Management Central (DMC). It attempts to contact the owners by letter, text or email.
If there is no response or payment, an application is filed in court. If that is served the owners have 25 days to defend it. If it's not defended the council can seek a court judgement, after a further attempt to contact owners.
When a judgement is obtained, proceedings in the High Court start three months later. In the case of Roberts Ave, the High Court issued its notice on July 29.
"The owners can at any stage pay what is owed or enter into a satisfactory arrangement to stop or pause the process," Smith said.
Horizons gets rates from about 108,000 units of property. The 16 who did not pay last year are a minority - and the council is prepared to take action to recover unpaid rates for the benefit of all ratepayers, Smith said.
