In my experience, having been a regional manager for a leading project management firm for six years, is that the council has demonstrated a very strong collaborative approach towards consenting and resolve of issues.
This is driven from within all levels of the business, with senior management being very available and open to receiving phone calls and assembling the right meetings, especially on larger commercial projects which carry a fair amount of financial weight and risk for clients.
The council's planning and building team have rallied to assemble trouble-shooting teams to overcome both resource and building consenting issues, including within the processing stage and onsite backlog issues.
An example of the team resolving complex issues, is their excellent service on Tauranga Crossing Retail development during 2016 where 20+ consents were being fired in together for tenant fit-outs, plus multiple consent amendments for the main development, the council assembled a go-to team to overcome consenting issues, a sincere well done to the team, all while supported by a top-down approach.
Don't forget the council has had to endure a huge uplift in relocation and office disruption with the services team working initially in ad-hoc accommodation, in my opinion, they held it together fairly well.
