The Rydges group of hotels and resorts have New Zealand pretty much covered and each property has dedicated staff to look after couples wanting wedding receptions.
Some resorts are also ideal for the actual ceremony and many of the hotels offer complimentary accommodation with a bit of pampering for the bride and groom.
There are Rydges properties in Auckland, Wellington, Rotorua, Christchurch and Queenstown (links below). As an example, Rydges Wellington is a landmark venue in the capital and there is a dedicated wedding coordinator heading a professional and friendly team. The hotel is close to Wellington Cathedral and Old St Pauls. The hotel’s Grand Space can cater for up to 230 guests and for more intimate receptions for 10 to 40 guests there are smaller venues or the sensational Plate Restaurant.
