Health boards say they are disappointed the NZNO had balloted members for more strikes ahead of talks this week. Spokeswoman Dale Oliff, the chief executive of Wairarapa DHB, said health boards had tried to meet the union in the middle and asked them to think more about a way forward, rather than planning further strikes. The strike options in the NZNO ballot were based on feedback from members which showed they favoured multiple strikes lasting 24 and eight hours, Wait said.

Nurses went on strike for eight hours on June 9.
